Not washing your hair does not make it grow.
And washing your hair does not make your hair grow either.
Hair growth is determined by your genetics and your overall health.
Not washing your hair though can lead to a buildup of oil and dirt on your scalp and hinder hair growth by creating an environment that is not healthy for your hair.
While washing your hair does not directly help your hair growth it can help keep the hair healthy.
Hair growth flourishes on clean and healthy scalps.
Washing your hair often enough but not too much can help your hair strands look better, feel better and be much healthier as well.
When washing your hair you should use shampoo when washing your hair only two to three times a week.
Reduce your shampoo use to only two to three times a week so you do not dry out or over wash your hair.
Doing this will also allow your hair to stay strong and healthy, leading to better long term growth.
You can also promote healthier and faster growth of your hair by eating more protein in your diet, using products made with caffeine, avoiding permanent dye, and reducing stress, among others.
Us humans are born with all the hair follicles we will ever have, including around 80,000–120,000 hair follicles on our scalp.
