Answer

Customers say this fragrance-free shampoo and conditioner set leaves hair feeling clean, soft, and silky without weighing it down. Many reviews highlight the gentle formula's effectiveness for sensitive or irritated scalps, with users reporting reduced itching and flaking. The conditioner smooths hair while maintaining volume, working well for various hair types including fine, curly, and gray hair. Common feedback notes the shampoo's strong cleansing power and that a little product goes a long way. Some users mention the shampoo can feel drying without the conditioner, and a few report the thick consistency makes dispensing difficult. Travel-friendly packaging receives praise. A small number of users experienced unexpected dryness or scalp irritation.

    The Best I’ve Ever Used

    This shampoo and conditioner set is great, very gentle and leaves my hair feeling nourished. It rinses clean and has no lingering scent. It’s great for the eczema on my scalp too. After a couple of uses, I ordered a backup supply for when I am finished with the first set.
