This product may work but for someone with dyed hair it’s not great. It really dried my hair out hugely and it felt quite stringy.
I didn’t use it again and wouldn’t recommend it if you have damaged dry hair normally.
Didn’t notice it helped in anyway either but perhaps would need to use it more
Definitely did nothing for me or my son as I bought it for the both of us. 1st you need an extra conditioner as it dried out my hair more and does not reduce frizz. 2nd it did not really better the condition of my scalp. It was maybe a little better for a day but on day 3 the dry itchy flaky scalp was back.
