Does blow dry­ing on cool dam­age your hair?

On a jour­ney to find the answer above I came across a love­ly lit­tle sci­en­tif­ic study (J Soc Cos­met Chem, pp 27–36, 1981) which showed that even with low tem­per­a­ture blow dry­ing hair nev­er gets back to its orig­i­nal mois­ture lev­el until it is soaked in water then air dried or placed at a much high­er humid­i­ty.

In oth­er words, heat dry­ing your hair actu­al­ly does dry your hair out.  To explain this, I will start off with a reminder of the basic struc­ture of hair.

This is what hap­pens when hair is wet through wash­ing. Water trav­els into the cor­tex.

When hair is wet, there are two options to dry it: air dry­ing and heat dry­ing.

I just have to say that if you are blow dry­ing to put an under curl in your hair with a round brush then you should blow dry fac­ing down the hair shaft so that you are not going against the cuti­cle. And your hair should be 90 % dry before you blow dry to style doesn’t mat­ter what type of hair you have. -Cos­me­tol­ogy stu­dent :-) P.S. I have an exam­ple down below

I have been blow­ing dry­ing my hair to get stretch to it because I don’t feel like putting a lot of time into my hair. But I have noticed that my hair is super char. I know now that I have to alter­nate between both dry­ing and dry­ing.

Hmm it looks like your web­site ate my first com­ment (it was super long) so I guess
I’ll just sum it up what I had writ­ten and say, I’m thor­ough­ly enjoy­ing your blog.
I as well am an aspir­ing blog writer but I’m still new to the whole thing. Do you have any rec­om­men­da­tions for novice blog writ­ers? I’d gen­uine­ly appre­ci­ate it.

Every­thing is very open with a pre­cise clar­i­fi­ca­tion of the issues.

Many thanks for shar­ing!

Thank you for the arti­cle. I have been nat­ur­al for 7 years. I also have two kids 8 & 4 who doesn’t have relax­ers at all. My 4 boy has very tight­ly curled hair that holds so much moister I only two strand twist his hair every oth­er week and he is good. My 8 yr old how­ev­er is my lil fash­ion­ista. She always wants her hair in dif­fer­ent styles. My prob­lem is both our hair is super dry. We both have eczema. And our scalps tend to flake and become very itchy and gets scabs in it. I wash… Read more »

Have you tried using essen­tial oils at all? I used to have a prob­lem with itchy scalp, but since I start­ed adding tea tree and /or laven­der essen­tial oil, itch­es and flakes have been nonex­is­tent :)

This arti­cle is quite infor­ma­tive. Think i’l go the grape seed.

Tasha Scott-Taylor

I’m so glad to have found this arti­cle.. I just start­ed blow­ing my hair 13 mos. Nat­ur­al I have no prob­lems but low set­ting is the key also grape seed or some oth­er great heat pro­tec­tion. Thanks for info

Dana

Thanks for the infor­ma­tive arti­cle! The pic­ture dia­grams real­ly help. I always blew out my hair just after a wash and con­di­tion­er but nev­er put any­thing on before because the hair would nev­er ful­ly dry up (like a sponge, it is!). The ends were always a wor­ry point for me. Now I’m prob­a­bly going to put some leave-in on and wait a bit before blow­ing it out on a low set­ting. You live and you learn!

Briichan

I’ve been blow dry­ing my hair since for­ev­er and nev­er expe­ri­ence a prob­lem but I think it’s all about hav­ing the mois­ture and using real­ly effec­tive heat pro­tec­tors. Do what­ev­er you can to pro­tect your hair :)

Hi I’ve been nat­ur­al for 2 1/2 years I’ve got­ten my hair straight­ened pro­fes­sion­al­ly once I tried it myself last week and was suc­cess­ful, how­ev­er when I wet it some parts of my hair wil not curl back up. Is there any­way to fix it? I’m so upset about this. ALSO I’m thinkng about hav­ing a bar­ber shape my fro will the clip­pers affect my curl pat­tern or oth­er styles? Thank you in advance!!!

I am not sure where you are get­ting your infor­ma­tion, but great top­ic. I needs to spend some time learn­ing much more or under­stand­ing more. Thanks for great info I was look­ing for this infor­ma­tion for my mis­sion.

First, I love this blog. I recent­ly became ful­ly nat­ur­al, tran­si­tioned for 15 months. I blow dry my hair on a low set­ting when I do a wash, I’m not the biggest fan of my shrink­age. I recent­ly learned about grape­seed oil as a heat protes­tant ~http://uneautrenaturelle.com/blog/2011/02/26/grapeseed-oil-as-a-heat-protectant/~ and hon­est­ly my hair feels incred­i­bly soft  when blow dry­ing my hair — I tow­el dry my hair real­ly real­ly real­ly good lol — put it in 6 sec­tions and apply a small amount of grape­seed oil to each sec­tion then blow dry on low — I apply Shea mois­ture after I do a blow out —… Read more »

Some­one I work with vis­its your blog fre­quent­ly and rec­om­mend­ed it to me to read too. The writ­ing style is excel­lent and the con­tent is inter­est­ing. Thanks for the insight you pro­vide the read­ers!

I used to blow dry at the begin­ning of my nat­ur­al hair jour­ney, but now I always air dry. The dry­er that I cur­rent­ly have does not have a cool set­ting. I’ve been con­tem­plat­ing get­ting a blow dry­er with a cool set­ting, and this arti­cle helped me in my deci­sion. Thanks much!

I blowdry my hair every once in a while,and when I do I tend to use reg­u­lar heat at the roots and grad­u­al­ly press the cool but­ton as I go down the hair. Some­one on here men­tioned Long­hair­dont­care and I thought I’d men­tion that there are two nat­ur­al hair ladies with that name,but the one I think the oth­ers are also refer­ring to is Long­hair­dont­care2011. I use tips by her as well and, yes her hair is doing fine. I think its about mod­er­a­tion and also mak­ing sure to use a heat pro­tec­tant and add oils,etc in before the hair… Read more »

Infor­ma­tive post!
I almost nev­er blow dry. I’ll do it if I’ve wet set my hair overnight and it’s still not com­plete­ly dry in the morn­ing, but even then I don’t use high heat and i’ve done it less than ten times in the past year. I’m still tran­si­tion­ing, so i’m ter­ri­fied of dam­ag­ing my new growth before i chop, which will real­l­l­ly be dis­cour­ag­ing to me ful­ly enjoy­ing being nat­ur­al!

Keisha

I can total­ly relate!!! Thank you so much for the info!!!!

Angela (@Gigee_B)
I’ve been com­plete­ly nat­ur­al for about 3 years and I think I’m one of few nat­u­rals that blow dry (and flat iron) some­what reg­u­lar­ly (once a week). I always do a deep con­di­tion­ing before blow dry­ing and I some­times may use a leave in (Knot Today). I also use a dime size of Chi Silk Infu­sion before blow dry­ing and before flat iron­ing. When I blow dry, I use a cool/medium set­ting and I nev­er put my flat iron on the high­est set­ting. My hair is a cou­ple inch­es past shoul­der length and has been doing fine with this regimen…I… Read more »

I think blowdry­ing in mod­er­a­tion is fine, and make sure to use heat pro­tec­tion and the right set­tings. Look at youtu­bers Long­hair­dont­care and Brit­tanyn­ic16 they use both heat and their hair is doing fine. I plan on fol­low­ing Long­hair­dont­care regime on my hair.

Me too!!

Great Arti­cle! Very well explained. I haven’t quite got the hang of blow dry­ing yet. I tried with a dif­fuse but it always seems to go hor­ri­bly wrong…

cassidybarrett

I don’t blow dry very often. I only blow dry on a low set­ting. But when I do my hair is as dry as the desert of Sahara. Thank you JC for this arti­cle. Loove your blog!
