RootStim Biotin & Rosemary Shampoo for Hair Growth — 16.9 fl oz, Sulfate-Free Formula for Thicker-Looking Hair and Scalp Care

RootStim Biotin & Rosemary Shampoo is a sulfate-free, nutrient-rich shampoo designed to support thicker-looking hair and a healthier scalp when used consistently.

This shampoo blends biotin with herbal extracts and targeted actives to address signs of thinning hair and scalp imbalance. The formula combines botanical oils, caffeine and a specialized diaminopyrimidine derivative with moisturizing agents to help strengthen strands, add volume and soothe the scalp without harsh sulfates or parabens. It’s presented in a 16.9 fl oz bottle suitable for daily or regular use in routines for both men and women.

How does this shampoo help hair look fuller?

The RootStim formula uses biotin and other fortifying ingredients to reinforce hair fibers and improve strand resilience. Regular use can help hair appear thicker by reducing breakage and enhancing body at the root. It doesn’t alter hair structure with harsh surfactants, instead supporting volume through conditioning and strengthening components.

• Biotin strengthens individual strands to minimize snap and split ends.
• Pyrrolidinyl diaminopyrimidine oxide helps target follicle support in the scalp area.
• Saw palmetto contributes to a balanced scalp environment that encourages fuller-looking hair.
• Aloe vera and argan oil add moisture and shine without weighing hair down.

What scalp benefits can users expect?

This shampoo includes rosemary oil, tea tree oil and ginger root to promote a calm, balanced scalp. Caffeine helps stimulate circulation at the scalp surface, while tea tree and ginger soothe irritation and reduce flaking for a cleaner-feeling foundation. These effects together support a healthier environment for hair to look its best.

• Rosemary oil and caffeine work to invigorate scalp circulation.
• Tea tree oil and ginger root help soothe and reduce visible flakes.
• Hydrating agents maintain scalp moisture without leaving residue.

Is this shampoo safe for colored or sensitive hair?

Yes — the formula is free from sulfates and parabens, making it gentler on treated and sensitive hair than many traditional shampoos. It cleanses without stripping color or natural oils, while aloe vera and argan oil replenish hydration. The absence of harsh surfactants reduces the chance of dryness and dulling after repeated washes.

• Sulfate-free cleansing that preserves color-treated hair vibrancy.
• Aloe vera and argan oil provide moisture and manageability.
• Formulated to minimize irritation for sensitive scalp types.

Which natural extracts are included and why do they matter?

This shampoo combines a blend of nine plant extracts drawn from traditional and modern hair-care research. Ingredients such as Polygonum multiflorum and Platycladus orientalis are included alongside rosemary and saw palmetto to deliver antioxidant and nutrient support to hair and scalp. Together they create a botanical matrix intended to nourish follicles and improve overall hair appearance.

• Polygonum multiflorum and Platycladus orientalis contribute traditional botanical support.
• Rosemary and saw palmetto offer balancing and strengthening effects.
• Combined plant extracts aim to provide broad-spectrum nutrient support.

Who is this for: RootStim Biotin & Rosemary Shampoo suits men and women looking to address visible thinning, boost hair body, and maintain a healthier scalp through a gentler, plant-forward formula. It’s a practical choice for people with color-treated, chemically processed or naturally sensitive hair who want a routine-friendly product that focuses on strengthening, hydration and scalp comfort. Use consistently as part of a full hair-care regimen for best results.
