Reviews

Love it!

"Highly recommend this shampoo if you have dry hair! I've tried many salon-recommended brands over the years and spent a lot of money on hair products, but this one has truly impressed me. I decided to give Tokyo Lab's green shampoo a try, and I loved it so much that I ended up buying the shampoo and conditioner for my husband as well. The scent is fresh and earthy without being overpowering, which I much prefer over heavily fragranced products. Most importantly, my hair feels thoroughly clean after washing while still staying soft and hydrated. Unlike many shampoos, it doesn't leave my hair feeling dry or stripped. If you struggle with dry hair, this shampoo is definitely worth trying!"

— Sarah (5/5)
