Yep, but sometimes the hair is simply destroyed. I follow a girl in Instagram and TikTok with the best hair you can imagine.

She grews up her hair a lot, but she decides to go platinum blonde, and her hair was completely burned. She cuts off shoulder lenght, then starts recovering her natural colour, then cut again because her hair was still destroyed, but finally she obtains a short but healthy mane, and she is in the way to grow up her hair again... a lustfull healthy mane.

She's doing it well. This is the way.
