I do prefer the genesis one, although it’s a good serum still 

Another incredible product from Kerastase - absorbs well, smells amazing and leaves my scalp and hair very happy. 

This product feels really nourishing on the scalp. However, I wouldn’t say it’s really helped my psoriasis/dry scalp. It smells lovely and feels like a luxurious product but there are definitely other products which are better for actually helping the scalp dryness. It feels like this just gives a soothing feel as opposed to actually doing anything to help the dry scalp! I do use it every now and again alongside my other hair products to help with my dry scalp.

Has helped my dry scalp massively without making my hair greasy. Also smells lovely. 

Upon reading reviews I thought I give it a try. I have dry scalp and this definitely. Using along with shampoo and conditioner from the same brand.
