must need for bleached hair
I've been using this on my roots after my monthly bleaching and it's so worth the money! My hair used to be so crispy and dry, even hair masks would only temporarily restore some softness and moisture. I only use it about once a week but it makes a huge difference. I do find the pay off isn't nearly as good on just coloured hair (since it's less damaging for me) but a must need for bleaching.

Noticeable Results
I have been bleaching and dying my hair for the last decade or so and after just one use I noticed (felt and saw) a huge difference in my hair. I’ve tried numerous products over the years of varying price points and brands and nothing has come close.
