Skin Research Institute KEEWEE Hair Growth Shampoo — Biotin & Niacinamide, Sulfate-Free Thickening Formula for Thinning Hair

SRILabs KEEWEE Hair Growth Shampoo is a sulfate-free, color-safe cleanser formulated with biotin, niacinamide, green tea and ginkgo to gently thicken hair and nourish the scalp.

This shampoo from Skin Research Institute combines clinically studied actives with botanical extracts to support the appearance of fuller, healthier hair. It’s designed to cleanse without stripping, soothe sensitive scalps, and add lightweight volume and texture to fine or thinning hair. Free from sulfates, parabens, silicones and dyes, the formula works in a routine with color- or keratin-treated hair while delivering a mild, herbal scent of rosemary, cedarwood and patchouli.

How does this shampoo help hair look thicker?

The formula uses biotin and niacinamide which are commonly included in hair care to enhance strand strength and surface texture, helping hair appear fuller. Green tea and ginkgo support scalp health and the sensory feel of thicker hair by improving manageability and bounce.

• Biotin and niacinamide for improved strand resilience and fullness.
• Lightweight volumizing action avoids heavy buildup.
• Botanicals add texture and natural movement.

Will this shampoo be gentle on my scalp and color-treated hair?

Yes — the low-pH, moisturizing formulation rinses clean without residue and is free of harsh sulfates and parabens. That makes it suitable for dry, itchy or sensitive scalps and safe to use on color- or keratin-treated hair without accelerating fade.

• Sulfate- and silicone-free to protect chemical treatments.
• Low-pH, hydrating base minimizes irritation and dryness.
• No added dyes or heavy fragrances that can aggravate sensitive scalps.

How does the scent and sensory experience feel in daily use?

The shampoo produces a rich lather that cleans thoroughly while leaving a light herbal aroma. The fragrance blend of rosemary, cedarwood and patchouli provides a calming, natural impression without overpowering the senses or masking other hair products.

• Rich foam for easy distribution and cleansing.
• Subtle herbal scent suitable for everyday use.
• Rinses clean to avoid sticky or coated residue.

How should I use it for best results?

Use on wet hair, lathering gently into scalp and lengths, then rinse. For optimal scalp health and visible improvements in hair body, incorporate into a regular wash routine and pair with a complementary conditioner or serum targeted to thinning hair.

• Wet hair completely before applying a small amount to scalp and strands.
• Massage scalp for 60–90 seconds to boost circulation and product distribution.
• Rinse thoroughly and follow with conditioner if desired.

Who is this for? SRILabs KEEWEE Hair Growth Shampoo is aimed at people with fine, thinning, or shedding-prone hair who want a gentle, clinical-meets-botanical daily cleanser. It suits those who need a sulfate-free, color-safe option and prefer lightweight volumizing without silicones or heavy waxes. If you want to support scalp comfort and smoother, fuller-feeling hair texture in a routine-friendly formula, this shampoo is a practical choice.
