Kerastese Elixir Ultimate shampoo is super hydrating and you don’t have to use much quantity because it’s that good! I love it but I can’t continue to use it because I have done some treatment to my hair and I could only use the shampoos they’ve given! This particular kerastase shampoo is still not available in India! Even the the third party websites sell it for twice or thrice the original price, which is almost 10k!! I got it last year and have the expiry until 2027. I have used a bit and loved it so much! and almost 180 ml is still there! Grab it for just 15% of it’s original price!!
