OGX Collectie Strength & Length Keratin Oil Shampoo 385 ml

This is excellent shampoo and helps keep my hair stronger

Honestly I haven’t seen any real difference in my hair at all, it smells nice, is just fine as a shampoo.

Been using this product for years after had keratin treatment since it's sulfate free

This does a good job of cleaning but not stripping, but haven't seen any real results from the strength of hair and such.

The first time using this shampoo I was incredibly impressed with how my dyed hair was looking/feeling. My hair smelt fresh and clean after. But after using this product for a month (I only wash my hair twice a week max due to the colour and alternate products) my scalp has been irritated and flaky to the point it bleeds and has caused a rash! It is Genuinely painful. I’ve never had this reaction from any hair product Incredibly disappointing and a waste of money in my opinion.
