This shampoo combines biotin and plant-derived oils with rosemary and zinc to support a healthier scalp environment and fuller-looking strands without harsh sulfates, parabens, or synthetic dyes.

The 10.1 fl oz bottle suits regular use and works on all hair types, including color-treated and sensitive scalps.

How does this shampoo help with thinning hair?

The formula focuses on strengthening hair at the root and improving strand body so hair appears denser. Ingredients like biotin, panthenol, and plant oils help fortify vulnerable hair and reduce breakage from mechanical stress.

• Biotin to support thicker-looking strands and improve texture.
• Panthenol for added moisture and elasticity to reduce snap-off.
• Argan and jojoba oils to nourish without weighing hair down.

Will it control oil and reduce dandruff?

Yes—key scalp-balancing components help regulate sebum while addressing flakes. Rosemary extract and zinc work together to refresh the scalp and help manage oiliness for a cleaner, longer-lasting feel between washes.

• Rosemary extract to stimulate scalp circulation and clarity.
• Zinc to support a balanced scalp environment and reduce flaking.
• Sulfate-free surfactants that cleanse without overstripping natural oils.

Is this gentle enough for daily use and colored hair?

The gentle formulation omits sulfates, parabens, artificial dyes, and strong synthetic fragrances, making it suitable for frequent washing and safe for color-treated strands. Its mild surfactants and conditioning agents preserve moisture and shine while keeping hair manageable.

• Sulfate-free base to minimize color fading and dryness.
• Light conditioning agents to detangle and smooth after rinsing.
• Free from parabens and harsh additives for sensitive scalps.

How should I use it for the best results?

Apply to wet hair, massage into the scalp to activate circulation, then rinse thoroughly; repeat if needed. Follow with a compatible conditioner or treatment to lock in moisture and support ongoing strength gains.

• Massage into roots for 60–90 seconds to boost scalp blood flow.
• Rinse and use a lightweight conditioner mid-length to ends.
• Use consistently as part of a daily or alternate-day routine for visible improvement over time.
