RootStim Biotin & Rosemary Hair Growth Shampoo — 16.9 fl oz, Sulfate-Free Formula for Thinning Hair

RootStim Biotin & Rosemary Shampoo is a sulfate-free, nutrient-rich cleanser formulated to help support thicker-looking hair and a healthier scalp for men and women.

This 16.9 fl oz bottle combines biotin, rosemary oil and a blend of plant extracts with targeted actives to gently cleanse while addressing common signs of thinning. The formula avoids sulfates and parabens, uses soothing botanicals and moisture-rich oils, and is safe for color-treated hair. Below you'll find concise answers to the practical questions shoppers ask most when deciding if this shampoo fits their routine.

How does RootStim shampoo support hair that looks fuller?

The shampoo blends biotin with pyrrolidinyl diaminopyrimidine oxide and saw palmetto—ingredients chosen to strengthen strands and reduce breakage that can make hair appear thinner. Regular use helps hair feel more resilient and may improve overall thickness appearance when paired with a consistent care routine.

• Biotin to strengthen and bolster strand structure.
• Pyrrolidinyl diaminopyrimidine oxide for follicle-targeted support.
• Saw palmetto to help address factors linked to thinning.
• Gentle daily cleansing that minimizes breakage from harsh surfactants.

What ingredients help the scalp feel healthier and balanced?

This formula includes rosemary oil and caffeine to encourage circulation and tea tree oil plus ginger root to soothe and refresh the scalp. Aloe vera and argan oil provide hydration, while a nine-plant-extract blend supplies botanical support for overall scalp condition.

• Rosemary oil and caffeine to stimulate circulation and vitality.
• Tea tree and ginger to calm irritation and help reduce flakes.
• Aloe vera and argan oil for moisture, softness, and shine.
• Polygonum Multiflorum and Platycladus Orientalis among nine extracts for botanical nourishment.

Is this shampoo safe for colored or sensitive hair?

Yes—RootStim is formulated without sulfates and parabens, making it gentler on color-treated and reactive scalps than many traditional cleansers. The milder surfactants clean hair without stripping natural oils, and calming botanicals help reduce the likelihood of irritation.

• Sulfate-free and paraben-free formulation.
• Aloe vera and argan oil to protect and hydrate colored hair.
• Suitable for most sensitive scalps when used as directed.
• Avoid contact with eyes; discontinue if irritation occurs.

How should I use this shampoo for best results?

Use on wet hair, lathering into the scalp and roots before rinsing; follow with a compatible conditioner for mid-lengths and ends. For consistent support, incorporate into a regular hair care routine and combine with gentle styling practices to reduce mechanical stress on strands.

• Apply to wet hair, massage into scalp for 60–90 seconds, then rinse.
• Pair with a lightweight conditioner to seal moisture.
• Use consistently—many users report improvements after several weeks.
• Store upright and keep away from extreme heat or direct sunlight.

Who is this for: RootStim Biotin & Rosemary Shampoo is designed for adults seeking a gentler, plant-forward shampoo that supports the look and resilience of thinning hair. It fits routines for both men and women, works with color-treated hair, and suits anyone who prefers sulfate-free cleansing with botanical ingredients rather than harsh detergents. If you want a daily-use shampoo that combines modern actives with herbal extracts to help hair look fuller and the scalp feel healthier, this formula is a practical option.
