No.301 Pure Hydration Shampoo

I recently had a keratin smoothing treatment done on my hair and needed to switch to a sulphate free shampoo. After searching high and low for something sulphate free in the bathroom cupboard I managed to find some Biology shampoo in my toiletries bag after a hotel stay and was thrilled to see it was sulphate free! I loved the natural scent and together with the Biology conditioner my hair was left incredibly soft, smooth and shiny. My hair has never looked or felt better since switching to Biology, plus my scalp no longer gets itchy or irritated (which I believe was due to using harsh shampoos). Highly recommend!

I was gifted a Biology Shampoo / Conditioner combo years ago, and have not used anything else since! With unruly hair, this is the only shampoo that doesn't make my hair either frizzy/dry or oily/limp! It's a great blend, that consistently delivers great results.

Keep clean my scalp and hair. Healthy Hair. Number ONE

My thick hair is fussy and the biology pure hydration shampoo does the job which is surprising because I've tried alot of supermarket and high end brands which end up drying my hair
