Let me guess, your hair keeps growing in at the roots BUT it never grows past the shoulders. This is very common and here are the 3 Reasons Why Your Hair Won't Grow
Friction: Your shoulders are creating friction on your fragile hair.
Haircut: Your split ends need a healthy trim or precision haircut to dust the damaged hair.
Protection: You need a flexible protein to fill the divots of the cuticle for protection.
Your shoulders are creating friction on your fragile hair. Your hair starts to flip the second it rests on your shoulders. When your hair reaches the shoulders you either can't wait for it to grow fast or get annoyed and chop it off. Your hair typically grows a half inch to an inch per month. If you aren't gaining at least a half an inch per month then the protein on your hair is weak and will result in breakage. By the time your hair reaches your shoulders in length, it's possibly several years old.
Your split ends need a healthy trim. Growing your hair out can feel like it takes forever especially when you are not trimming your hair. Remember your neck hairs have an extra 3 inches of length before the hair by the ears can meet it. For those who are looking to grow your hair passed the shoulders then keep getting regular trims every 2 months to trim the neck hairs until the sides meet. Receiving a precision hair cut to dust the damaged hair will help your hair grow. This is where the stylist will literally cut only the split ended hair off. Think of your hair like a piece of fabric and if the jeans are frayed then it will continue to fray until you cut it clean above the fray. Otherwise, your jeans will continue to fray higher and higher while losing length.
You need a flexible protein to fill the divots of the cuticle for protection. Traditional color uses ammonia to swell the cuticle in order to penetrate. The cuticle becomes rough and initially creates body. But as the hair continues to grow the cuticle becomes more weak and need protein to build the cuticle back up to strengthen & smooth your hair. It's important to use a flexible protein to help hug all the divots of the cuticle. The best flexible protein is amaranth protein found in Trinity Protein Repair Tonic.
The 3 common reasons why your hair doesn't grow is your shoulders are creating friction, your split ends need cut and you need a flexible protein to fill the divots of the cuticle to protect and strengthen your hair.
