oely Biotin Hair Growth & Thickening Shampoo 10.1 oz – Sulfate-Free, Root-Activating Formula for Thinning Hair

oely Biotin Hair Growth & Thickening Shampoo is a sulfate-free daily cleanser formulated with biotin, botanical oils, and rosemary to strengthen roots, control oil, and add visible thickness to thinning hair.

This shampoo blends plant-derived ingredients and targeted actives to support scalp health and thicker-looking hair without sulfates, parabens, or synthetic dyes. Designed for men and women, the formula focuses on root activation, oil balance, and gentle cleansing so you can use it regularly as part of a hair-strengthening routine. It’s intended for all hair types, including sensitive scalps, and pairs well with a lightweight conditioner or scalp tonic.

How does this shampoo support thicker-looking hair?

The formula delivers biotin and panthenol to strengthen each strand while botanical oils help improve hair elasticity and fullness. Regular use helps reduce the appearance of thinning by reinforcing hair from the base and protecting against breakage during washing and styling.

• Biotin and panthenol for strand reinforcement and shine
• Coconut, jojoba and argan oils to condition without weighing hair down
• Root-activating botanical extracts to promote fuller appearance

Will it help oily scalps or dandruff-prone hair?

Yes — the shampoo contains rosemary extract and zinc, ingredients selected to balance scalp oil production and help control flaking. It cleanses gently to remove excess sebum and product residue while maintaining the scalp’s natural moisture barrier.

• Rosemary extract to support circulation and oil regulation
• Zinc complex to target dandruff-prone areas
• Sulfate-free surfactants that cleanse without stripping

Is this safe for color-treated or sensitive scalps?

The sulfate-free, paraben-free, and dye-free formula minimizes irritation and helps preserve hair color by avoiding harsh surfactants and unnecessary additives. Users with sensitive scalps typically find it gentler than conventional shampoos, but a patch test is recommended if you have a history of reactions.

• No sulfates, parabens, artificial dyes, or synthetic fragrances
• Gentle cleansing suitable for daily or frequent use
• Works with color-treated hair when paired with color-safe conditioners

How should I incorporate it into my daily routine?

Use the shampoo as your regular cleansing step: wet hair, massage a small amount into scalp and roots, then rinse and repeat if needed. For best results, follow with a lightweight conditioner focused on hydration and gentle detangling, and use a scalp serum or leave-in treatment occasionally to support targeted root care.

• Apply to wet hair, massage into roots for 60–90 seconds
• Rinse thoroughly and use conditioner on mid-lengths to ends
• Pair with scalp treatments or a biotin supplement routine for added support
