Incredible

I recently damaged my hair from bleach babylights and this has resurrected it. Hair feels and looks incredible even after one use. A definite repurchase, shame about the price.

My hair is on its recovery journey and it’s quite dry and damaged. I thought I wouldn’t see my curls for years, but after washing and a mask I used 3-4 pumps on towel dried hair and my hair was soft and curly. I’ve seen consistent results from the first use and I would recommend it!

This leaves my dry and damaged hair so soft and shiny. I dye my hair every 4-5 months which dries it out but this keeps my hair soft and healthy

Absolutely transformed by hair once I got the knack of how best to use it. Absolutely worth the splurge
