I purchased this as they used it when I went for a head spa and it made my scalp feel so light ! It was amazing ! I used it alongside an expensive shampoo thinking it was the shampoo but when I ran out of this and kept using shampoo my scalp changed ! So don’t spend £130 on shampoo and just buy this with your usual shampoo!
