I have bleached and color treated blonde hair. For years I used Shimmer Lights shampoo on my hair any time it started to get brassy. I was complaining to my hair stylist that in between seeing her my hair had started to get really brassy. She recommended the alchemic conditioner instead of Shimmer Lights. I bought this container months ago and still have about half of it left. I use it about once a week to keep my blonde fresh, and get rid of any brassiness. I have long very thick hair and I was worried that the product would not last me long and would not be a thick or moisturizing even conditioner for my hair. Surprisingly it did a great job conditioning! I gave it 4 stars instead of 5 because I don't love the scent. I am very sensitive to fragrance and it's a little too floral for me, and started to give me a headache. Now I use a little bit of Morrocan Oil conditioner after I wash this out to get rid of the scent.
