I washed my hair 6 hours ago and it's still wet!
Granted, I have been wearing a beany hat all day and it is in plaits but even when it's loose my hair does take a long time to dry. The key driver of the rate at which hair dries is its porosity. Porosity refers to how easily water and other chemicals can diffuse into and out of hair. If the outer layer of the hair fibre, the cuticle, is very tightly bound and lies very flat the hair is not very porous. This type of hair is quite resistant to the entry and exit of chemicals including water. If the cuticle layer of hair has been damaged, it's weak and much more porous. Porous hair dries much more quickly than non-porous hair. Porous hair once moisturised loses that moisture much more quickly than hair that is not porous. ![]()
Other environmental and external factors influence the rate at which hair dries:
According to The Science of Black Hair, an intensely hot blow dry for a short period of time (10 - 20 minutes) is far more damaging than much milder heat application for a longer period of time, e.g. sitting under a hooded dryer for 45 minutes. Keep these factors in mind when you want your to dry fast!

Ok... is it just me? Both pictures are labeled as a damaged cuticle. Surely this is an oversight.

My hair has a very very itchy area and that side is thin and not the same length as the other side, Do you think it can recover or is it permanently damaged?

If you use a lot of Shea butter, STOP. Shea butter coats the hair shaft as well as the scalp (depending on how it's applied). When it leaves a coat, the hair is unable to soak in moisture, causing the hair to remain dry. Hope this small tip could help! Comments are closed.
