Tim Bailey –
I’ve used this duo after multiple bleach jobs and noticed my hair felt softer and more manageable within a week. The shampoo cleaned without drying, and the mask gave immediate bounce and strength. No more frizz or split ends.
Jasmine Taylor –
Great for post-chemical treatments. The detox shampoo removed residue well, and the mask worked fast. My hair looks healthier and feels smoother after just one use.

After using this duo twice, my hair has regained volume and shine. The repair is noticeable even on fine, damaged strands. I’d recommend it to anyone with coloured or chemically treated hair.
