3 Ways Daily Co-Washing Can Damage Hair

Via The Beauty Brains

Illegal fireworks asks…I have really dry curly hair. Will it damage my hair if I condition it everyday?

The answer depends on HOW you condition your hair. Rinse out conditioners are the worst – not because the conditioner itself does any damage but because of the processes of washing,  rinsing and drying.

Three ways conditioning is bad:

First, if you used any shampoo prior to conditioning you may be stripping your hair of moisturizing oils.

Second, just wetting and drying your hair (even without shampoo) causes the cuticle to expand and contract which can be weakening because it creates radial cracks in the outer cuticle layers.

Third, towel drying your hair always involves some degree of frictional abrasion that can crack and scrape off even more cuticle.

Leave in conditioners can be less damaging

If you’re not washing and wetting your hair, leave in conditioners are just fine. At most they require just a little combing to smooth them through your hair.

If you’re washing your hair anyway (or at least getting it wet for some reason) it’s better to go ahead and condition. But if you can skip a shampoo-wet-dry cycle and use a leave in conditioner instead, you’ll avoid opportunities for damage.

Ladies, have you experienced damage from daily co-washing? How did you prevent against it?

  1. I disagree, when i co-wash my hair every other day my it makes my hair stronger, where my hair was prone to breaking and shedding a lot co-washing has drastically reduced it. i still use a Shea butter leave in conditioner before i style, but i have found co-washing very beneficial for my hair

    • I agree with you Maya. In the summer months, I cowash 2-3xs per week and do a lot of wash and goes. My hair loves it.

      I think it depends on how the cowash is done. I don’t do the heavy duty scrubbing like the lady on the pic. What I do is put my hair in 5 sections – front, two sides and two back portions and cowash in sections by just applying the condition down the length of the sections, finger or widetooth comb detangle each conditioned section, and twist the section. I let the conditioner sit in my hair while I shower and then rinse the hair out while still in the 5 twists. So there isn’t any heavy manipulation but my hair is benefiting from the extra moisture provided by cowashing.

        • Depends on how I’m wearing my hair the next day. If I’m in a semi-wash and go mood and am not interested in definition, then yes. If not, I will seal water moisture w/ olive oil and Shea Moisture Curl Smoothie, separate the twist into 8-16 twists (depending on how much of a defined look I want) or 6-8 cornrows (again, amount depends on how defined I want).

          I am a big cowasher and only use shampoo when my hair feels particularly filmy or sticky like when I use gel. I don’t use gel on a regular basis because while it makes my twist/braid outs look fab, it makes my hair so sticky feeling.

          • So its okay to just use a leave in conditioner and only use shampoo when hair feels filmy or in desperate need?

          • I’m all about doing what works best for your hair and I don’t believe in cookie cutter rules. So, if that works for you, go with it.

            In the winter I only cowash once a week but I spritz my hair with water and apply olive oil and some sort of leave in (conditioner, hair product) on a daily basis. I am a firm believer that water is the best moisturizer and my hair needs lots of moisture. Now, I don’t know if its just habit that I feel the need to do some sort of complete soak of my hair once a week at minimum, or if my hair simply needs to be cowashed at least once a week. But, I know it works for me, so I’m sticking to it.

          • I agree with you Yoco, water is the best moisturizer. I wet my hair everyday. I do use gel on my wng’s so this also prevents excessive build-up—but for me simple water is the best moisturizer. If I don’t wet my hair I find that it tangles (and of course feels dry). I wash/co-wash my hair twice a week.

            My hair has been flourishing using this system. (I acknowledge everyone’s hair is different.) But the author mentioned using a leave-in as a sufficient moisturizer: I want to put forth that leave-ins are usually used to seal in and retain moisture; if the hair is already too dry you are just sealing in dryness and having product build-up on your hair ::shudders:: I hate product build-up, need moisture retention and avoidance of tangles– water rinse or spritzing is a must for this.

            Don’t be afraid to get your hair wet–it is a major advantage of being Natural! :)

    • Agreed. When I co-wash daily, my hair grows like weeds and it is soft and supple.I think strand thickness is a major factor in being able to co-wash daily.

      Ladies listen to your OWN hair! These people are not scientist and are quite irresponsible using declarative statements.

  2. I co-wash everyday, if not everyday its every other day. I do not use shampoo at all. If I do its onces a month. So far conditioner only washing works great for me. My conditioner is mixed with grapeseed oil after co-washing I do the two strand twist and let my hair air dry. My gel for the two strand twist is also mixed with shea butter, coconut oil and grapeseed oil. I never ever use a leave in conditioner because of the oils in my regular conditioner and gel. My hair actually loves it when I co-wash everyday. No problems with dryness or breakage.

  3. What about damping your hair everyday? As in spraying it with a little water before applying leave-in? Still damaging?

  4. I completely disagree with this article. I’ve been co-washing my hair more often for the curly girl method and it’s one of the best things Ive decided to do for my hair. My hair is always soft and looks a lot healthy.

  5. Well, I’m about to take my chances and co-wash at least every other day, if not everyday. I plan to minimize any damage that might be done by constantly applying coconut oil and occasionally adding coconut cream/milk to my hair. I really don’t see how you could co-wash too much. Maybe if you co-wash three times a day. lol.

  7. oh good lord. just existing causes hair breakage.

    to me, the better question on the breakage meter is:

    what’s going to cause the most significant breakage?
    what type of handling may contribute to the least breakage?

    on the overall scale, i’m sure that putting conditioner in your hair and washing it out every day rank pretty low on the breakage meter.

    damage is a given. the idea is the minimize it through certain techniques. co-washing every day may be a technique that rates low on the damaging scale. it certainly isn’t up there with flat ironing, blow drying, dyeing, etc. so, it still may be a good option for people who do it and like the results.

    sometimes, this stuff is so alarmist.

    • I agree! It seems that every time I visit one of these websites there is an article about how something is damaging to hair. Seems like you can’t do anything without damaging it. Can’t comb it, can’t wash it, can’t blow dry, probably can’t even look at hair without damaging it.

      • LOL@HK. THANK YOU! Just too much drama. What works for one works for them and that’s it. These kind of comments can really put people against being natural. Don’t do this don’t do that. Don’t say this don’t say that. Please, i take advice and work with it and if it works it works if it doesn’t i’m not going to publish a bible about it.

      • Exactly! No wonder a lot of women are hestitant about going natural, some of these sites make it seem like you cant do anything to your hair without it breaking. DONT CO WASH, DONT USE SHAMPOO, DONT BLOW DRY, DONT WEAR YOUR HAIR OUT OR YOU WONT RETAIN LENGTH! At the end of the day its all about moderation with your techniques, taking your time when combing your hair or manipulating it, and keeping it moisturized. Goodness. JUST STOP IT, PLEASE! lol

        • +1! Natural hair does take a lot of work, but it does not have to be as complicated and/or restrictive as it is made out to be at times!

          As Tonya said “moderation with your techniques, taking your time when combing your hair or manipulating it, and keeping it moisturized” WILL keep you hair healthy and growing. It’s really not rocket science!

  8. I guess I don’t even understand the question which is probably why the response is not that great. Is she worried about dryness or damage or both? Or breakage? Co-washing will definitely help with dryness by replacing a drying shampoo. Any type of handling of the hair will lead to some breakage more or less. Someone who manipulates their hair daily will probably deal with more of that than someone who handles their hair on a weekly basis on a cumulative basis. To deal with damaged hair, other steps besides co-washing are necessary such as protein treatments.

  9. I got water damage from constantly co washing my hair. To rectify it, I told the hair dresser to just cut it off, she encouraged me to just let it grow out evenly …but I’m an all or nothing kinda girl, so I told her to just cut it.

  10. Ladies, first you have to read the article. It is not about co-wash can possibly damage you hair. It is the opposite. I think the blogger must change the title. I do co-wash every day or as needed. This is one of the best regimen to manage after big chop hair, while you are getting your length. In the mean time this is the easiest way. Once, I get enough length to do more hair style, the co-wash will be less often. So girls, enjoy every state of you natural hair growth! Beba…

  11. I’m not a “co-washer,” but I also disagree with this article. I think the damage, if any, that is caused by wetting your hair is minimal when you weigh it against the need to clean your scalp! Why isn’t anyone talking about that?

    After I wash my hair, my scalp feels great! It doesn’t itch or hurt, and my hair smells good, looks better, and is moisturized. I always feel like I have just gotten a massage after I wash my hair. By the way, I happen to use a medicated shampoo for parts of my scalp, and a mild shampoo for the rest because my scalp is sensitive. I think washing your scalp every 3-4 days is ideal, assuming it is practical for your styling choices and lifestyle.

  12. In my experience I don’t like co washing because my hair still feels dirty and too oily. I like to wear my hair straight in the winter and natural in the summer. When wearing it straight if I don’t shampoo it doesn’t straighten good and it’s weighed down from dirt and oil. Sigh, what to do?

    • I definitely understand what you are saying. On top of that I find that because I have dandruff my hair was itchy and greasy. HOWEVER, i read another article on co-washing and this is how to wash it and get it clean: take a cheaper conditioner say V05 and work through your hair massaging the scalp to loosen dirt. Then take a quality conditioner and work through and let set then rinse. I find for myself I have to massage with the 1st conditioner once to loosen dirt and then a second time to really get the dirt out–its harden to get dirt out with conditioners because they dont suzzed up the same way shampoos do. Then, I go back with my quality conditioner and let it set. I call the second round of the cheap conditioner the curtesy flush *really gets the dirt out lol*. I’m new to the cowashing but this works. What I think I will do is just do a simple conditioner every/every other day and do this procedure once every 2 days. And only wash with shampoo when I really need it. attached a pic with myhair showing in the one kissing the baby

  14. I want to know the sample size, how many experiments were done, and how many subjects actually had textured hair to prove that Water damages the hair because of the expansion and contraction. I just don’t buy it. If that was the case then all of the 2 and 3 type curlies that wash their hair every day (with shampoo) would be bald. I have type 4b or 4c hair and I co-wash my hair nearly every day. It has been incredibly beneficial. If your hair is dry it is not because of CO-washing-it means that you are using the wrong products.

    • I’m not a big fan of co-washing either. I dilute SLS free shampoo (JASON jojoba). It leaves my hair soft & clean w/o feeling stripped. Works for my 4-something hair.

    • You can try to shampoo your hair less often, re-examine the amount and types of products you put in your hair, OR use a No-Poo or Low-Poo shampoo. Maybe you will have to do all three or some combination.

      Sulfates are what make shampoo (and dish detergent and clothes detergent)make suds. The more sudsy your shampoo, the more it wll dry your hair out.

      Try a shampoo that has no sulfates, or low sulfates and water it down then follow with a deep conditioner and leave in conditioner. Try to make sure your hair is CONDITIONED properly rather then trying to get moisture from products ad see if that makes a difference for you.

    • @Paola I co-wash every other day and stopped using shampoo for the past three months. I was using Suave Naturals Almond and Shea Butter as a conditioner and a leave-in. I never felt any build up or felt like it weighed down my hair. It never left my scalp and hair feeling like it was still dirty either. However, I switched to using Aussie Moist conditioner as a leave-in (been using it for 2+ weeks) and since it causes some build up, I’ve started using Neutrogena Clarifying Shampoo (focusing more on my scalp). Suprisingly, it didn’t leave my hair feeling dry and there wasn’t alot of soap suds when I lathered. I plan on using this shampoo once a week to get rid of build up! Hope this helps : )

  17. I don’t co-wash everyday. I don’t really see the need to but everyone is different. If it works for you, that’s great :) I moisturize my hair every other day and co-wash once a week.

    I don’t wanna say that the author was wrong because maybe there have been women that have experienced negative effects from daily co-washing. Some hair may be more fragile because of genetics. Haha but from what I can see it benefits most of you.

  18. Since I workout 6x a week I rinse my hair out every other day. It’s a necessity because when I don’t the salt from the sweat hardens and dries out my hair. The only damage I sustain from CO-WASHING is when I pull my wet strands back into a ponytail for the day. This has substantially stretched out the front of my hair and now I have straight pieces in the front.

  19. I fee that my scalp is an extension of the skin on my body, which is a living, breathing organism. Like my body, it makes since to me that it should be washed everyday. We are creatures of habit and somewhere growing up we learned to wash our hair once a week and take a bath everyday. Now my mom has four girls so I can see why she did not or could not wash her hair as well as ours everyday. I believe week better as we know better.

    There have been weeks that I co-wash everyday, however, now my schedule only allows me to co-wash once or twice a week, however, I started listening to my hair and wash when I need to.

    I too believe that conditioner washing can only benefit the hair. It is the styling products that we can mess up with (cause build-up, etc.). How much is too much? Just like you do not want to have a funky body from not taking a bath or shower, I am equally sure no one wants to walk around d with funky hair.
