    Love love

    I normally use kerastase but wanted to give this a try. I loved that it does not leave your hair greasy and it does what it says!

    Love this!

    Love the very light scent, the moisture it provides my hair, and the way it absorbs into my scalp without feeling greasy. I’m looking forward to seeing results.

    Hair growth in a month!

    Gifted by caudalie Absolutely loving this hair serum. I struggle finding serums that won’t leave my hair a greasy mess and that I can apply everyday without a wash. This is the perfect consistency for that! If anything it’s making my hair look more voluminous. I’ve been using it for almost a month now and am noticing small baby hairs at my hair line, and my side areas look much fuller than before. I can so recommend this!

    works

    I really noticed a difference from the very first application—it’s impressive. I’ve been struggling with hair loss for a long time.

  • 2 weeks ago

    Good

    I think you need to use at least two bottles to get real results, but I did notice minimized dandruff which is great! Does definitely help hydrate the scalp.
