Recommend for Bleached Curls

I was advised to purchase this by my hairdresser after adding blonde highlights to my naturally curly hair. Despite the high price I’m glad I did as it’s really helped the condition of my curls post bleaching.

Been using this for a while, it’s nice but I still prefer Olaplex
