I bought the new Tresemme Expert Biotin Repair mask at the weekend and wow it's brilliant.
I just combed it through left it for 5 mins and rinsed out and it's made my bleach damaged hair look like nice silky normal hair again. It's a small revelation! I highly recommend this as a much cheaper alternative to the Opalex at home treatment.
*Disclaimer: I don't work for Tresemme, I'm just a normal person.
