Before I discuss how this product worked for me let me fill you in on my hair type, my hair is coarse, dry, frizzy and beyond brittle! I failed the snap test horribly before my first wash.
The clear bottle provides you with a good marker on how much product you have and at 250ml there is plenty to use! I love how this product lathers and works through the hair while you wash, I had no troubles with knots as my hair never felt 'stripped' by this shampoo. After my first wash my results were minimal, slightly less frizz was the only result I saw. By my second/third/fourth wash my hair had become more supple and hydrated. Do not be fooled by your understanding of oil in hair, my hair was in no way weighed down and there were no traces of anything on my roots and scalp after rinsing. My results were the same on air dried hair and heat treated hair.
I do like the results I got from this shampoo and the smell is very nice not too perfumy. I had to double the shampoo however to get a good lather up in my hair however I do have long thick hair. My hair feels nice and clean looks shiny and soft. I still get a bit of frizz so will need product to tame that.
Tips: May need to use more than your usual amount to get a good lather.
