COOLKESI Biotin Shampoo and Conditioner Set, 2 x 16 oz with Tripeptide

Some hair routines prioritize a thorough scalp cleanse, others focus on softness and shine. This shampoo and conditioner set brings both steps together with biotin, tripeptide, and onion extract in the shampoo, plus moisturizing ingredients for the lengths. Want a routine that addresses scalp cleansing and hair conditioning in one pairing?

What matters most

The shampoo combines biotin and tripeptide with onion extract and vitamin E as part of a formula marketed for fuller-looking hair and scalp care. Citric acid and rosemary extract are included for a clarifying cleanse, while the creamy foam is designed to lift residue. The companion conditioner features squalane, Moroccan argan oil, and glycerin to help hydrate and smooth hair, supporting a softer feel and a polished-looking shine.

This pairing is useful when you want more than a basic wash: the shampoo focuses on cleansing the scalp, and the conditioner adds moisture along the hair lengths. The set is described as suitable for men and women and for curly or straight hair. It is also formulated without parabens and is not tested on animals.

Who it’s for

Choose this set if your routine calls for a shampoo with scalp-cleansing ingredients alongside a conditioner geared toward softness and moisture. The 2 x 16 oz format gives you a shampoo-and-conditioner pairing for regular use, rather than a single-purpose product for just one step. Its blend of cleansing and conditioning ingredients can fit routines addressing residue, dryness, frizz, or hair that looks flat and could use a fuller appearance.

Customer feedback often highlights hair feeling soft, clean, and shiny, with some buyers also describing a thicker-looking result. Opinions on lather are mixed, so the amount of foam people experience varies. These impressions describe individual experiences, while the product’s ingredients and two-step format provide the clearest guide to what the set is designed to do.

Everyday use

Apply the shampoo to wet hair, massage it gently into the scalp, and rinse thoroughly, repeat if needed. Follow with conditioner along the hair length, leave it on for 3–5 minutes, then rinse. Keeping the conditioner focused on the lengths makes the two steps easy to distinguish: cleanse at the scalp, then condition where softness and moisture are the priority.

For example, after a day when styling products or everyday residue are on your hair, use the shampoo as your cleansing step and finish with the conditioner to smooth and hydrate the lengths. The set’s combination of scalp-focused cleansing ingredients and conditioning oils makes that routine straightforward without adding a separate shampoo and conditioner pairing.

When it makes sense

This set makes sense for shoppers looking to combine a biotin-and-tripeptide shampoo with a moisturizing conditioner in one coordinated routine. It brings together ingredients associated with scalp cleansing and hair conditioning, with a focus on clean-feeling roots and softer, shinier lengths. If those are the priorities for your regular wash routine, the paired 16 oz bottles offer a practical way to give each step its own role.
