How Long Does It Take to Grow Out Natural Hair?

“How long will it take me to grow out my hair and reach my hair length goals?”

This question, and the many variations of it, is one of the most frequently asked hair questions I get. Unfortunately, it is also one of the toughest questions to answer. Many factors determine the length of time it takes for a person to grow out their hair and reach certain hair lengths. This article will try to offer some guidance for length planning. As you read, bear in mind that the time estimates listed for growing out the hair in this article are just that-estimates. You’ll see that by the number of “typicallys and generallys” sprinkled throughout the article. There are just so many factors that influence when hair length goals are met including genetics, your anatomical structure, and the level of care and attention you give your hair. Growing out the hair takes years of consistent, diligent care. Though many folks are interested in achieving longer hair lengths, they do not realize the significant time investment that is involved in growing hair. Unrealistic goals and magical creams and potions that promise faster growth results but fall short on the promises make it easy to become discouraged. The only tried and true method for growing out the hair is good old fashioned time. Never fails!

General Considerations

Hair grows approximately ½ inch per month, for a total of six inches in one year. This rate is an average across races. Asian hair grows slightly faster than this average, Caucasian hair grows near the average,and black hair trends to grow at or just below this average each month. Genetics will also influence how close to the average ½ inch you get each month. Ultimately, the estimated time length for growing out the hair and reaching any hair length goal depends on two main factors: each individual person’s hair growth rate and their retention ability. A faster hair grower will always reach their goals sooner than a slower grower if the retention rates are the same. A slower grower will reach their goals consistently over a faster grower who poorly retains their length. Two individuals may grow their hair at the same exact rate while only one reaches her hair goals consistently, this is an instance of an ends retention problem for one of the growers. I often hear ladies say, “My hair is not growing, no matter what I do”-and for chemically relaxed ladies in particular we see that this is not true every 8-10 weeks when they are going in to have their relaxer retouched! Your hair is ALWAYS growing, retention may be the issue.

The Typical Process

Growing out the hair tends to follow a certain path. Generally changes in the look, thickness, and feel of the hair come first. Usually it is within the first 3-4 months of your hair journey that you’ll notice these improvements in thickness, and this tends to happen before you ever see any additional length. The big difference in length usually happens around 6-8 months into the journey provided you have been diligent with your hair care. For me, I started my journey in about June/July of a year, and noticed my hair getting thicker around October of the year. By December and January, I could see the length starting to come as well.

The timetable below is one that is suggested by the literature, but my personal hair growing experience has been different with personal setbacks, style changes, and trims all throughout my journey. Be forewarned, it is a very generalized timetable and not something you should feel compelled to follow to the letter. I certainly have strayed from the mark! Please note that this timetable is so open to interpretation that I almost hesitate to post it here, but some may find it useful!

    I have been on my journey for the past four going on five years and my hair is not past my shoulders, and it is uneven everything is off and the center is the shortest. My hair is the longest in the back and it SHOULD be longer, I know I fucked up but still trying to figure out where.

    It has been 2yrs 7mnths since I transitioned, and it was just yesterday that I realized I’m at little below shoulder length but not quite bsl. I’m surprised and very proud of my progress. Can’t wait to see what the next 2 yrs will have in store

    My goal is Arm pit length but i noticed that my hair appears to have slowed down in growing idk why. i’m not taking meds and i keep my hair in protective styles for 90% of the time idk what’s going on ??

      That’s the problem, your hair is in too many protective styles. You’re not letting it breathe. You should take the time to wash it out and cleanse your scalp often then let tour hair breathe. Using protective styles too often might cause product buildup and Everytime you loosen your hair, it will real or be dirty. The dirt clogs your hair pores, as a result your hair can’t breathe enough to grow.

        Ya i noticed that over the summer and so now i just leave my hair in a protective style for 30 days and than shampoo and leave it out for two weeks to breath. As of right now most of my hair is either 10 to 11 inches but i needs to be trimmed but this time around i’m going to try to dust my own hair because when i trim i’m right back to square one :(
