        Great For Color-Treated Thin Fine Hair

        My stylist remarked about how I had a lot of new hair coming in! My ends are healthy as well.

        Refreshing

        The lightly lingering aroma is definitely a positive. Shine and strengthening are now very evident. An allover positive impact. I will continue to purchase this product as well as the others I have become fond of. Well worth their cost.

        Love limited and clean ingredients. Scent is great, conditioner leaves my hair softer / silkier.
