# COOLKESI Biotin Shampoo and Conditioner Set, 2 × 16 oz

The COOLKESI biotin shampoo and conditioner set pairs cleansing and conditioning products in a two-bottle routine. The listing promotes biotin, tripeptide and onion extract for fuller-looking hair, plus moisturizing ingredients and scalp cleansing, but these are product claims rather than verified hair-growth results.

## Specifications

### Identity
- Brand: COOLKESI
### Package details
- Listed set size: 2x16oz
- Package dimensions and weight: 8.15 x 5.39 x 2.8 inches; 2.6 pounds
### Claimed ingredients and attributes
- Stated formulation claims: Free from parabens, never tested on animals

## Before you buy

- The listing claims the formula is gentle and less likely to cause allergies, but provides no substantiation for an allergy-related guarantee. Review the ingredient list if sensitivities matter.
- The listing describes hair-growth and anti-loss benefits, but supplied evidence does not establish that the set regrows hair or prevents hair loss. Treat fuller-looking hair as a claimed appearance benefit, not a demonstrated treatment result.

## A good fit for

- Shoppers seeking a shampoo-and-conditioner set with listed moisturizing ingredients and a specified conditioner routine.
- People interested in trying a fragranced hair-care set marketed for shine, softness and fuller-looking hair.

## Less suited to

- Buyers seeking proven hair regrowth or a medically established treatment for hair loss.
- Shoppers who need confirmed ingredient details to avoid a particular sensitivity, since a complete ingredient list is not supplied here.

## Customer feedback

Customer feedback highlights soft, clean-feeling hair, pleasant fragrance and shine, with reports that hair looks fuller or thicker after use. Some customers also appreciate the set's perceived value and say they can go a couple of days between washes. Lather is a point of mixed experience. These reports may help shoppers gauge routine feel, but they do not verify the listing's hair-growth claims.
