GROEI Onion Biotin & Rosemary Shampoo and Conditioner 2‑Pc Set — Sulfate-Free, Moisturizing

This two-step system combines onion extract, biotin and rosemary to help revive dry, fragile, or dull hair without sulfates. The shampoo gently removes buildup while delivering strengthening nutrients to roots; the conditioner seals in hydration and smooths strands for improved manageability. Formulated to be suitable for all hair types, including color-treated hair, the set is intended for regular use as part of a simple at-home routine.

How does the onion extract and biotin formula support hair strength?

The blend of onion extract and biotin focuses on nourishing the hair shaft and scalp environment to reduce breakage and promote hair that looks fuller and more resilient. While not a medical treatment, these ingredients are chosen to fortify strands and improve their texture with ongoing use.

• Onion extract: provides sulfur-rich compounds that can help improve hair texture and appearance.
• Biotin: a vitamin-linked ingredient that supports healthier-looking hair when used consistently.
• Sulfate-free cleansing: preserves natural oils to prevent over-drying.
• Daily-friendly formula: gentle enough for routine use without stripping moisture.

Will this set hydrate dry or damaged hair?

The conditioner is formulated to lock in moisture while smoothing frizz and enhancing shine, making it a supportive step after the shampoo. Its moisturizing base combines with rosemary to leave hair feeling softer and more manageable after regular use.

• Moisture-lock conditioning helps retain hydration along the hair shaft.
• Frizz-smoothing agents improve combability and shine.
• Rosemary leaf extract balances scalp oils for a refreshed feel.
• Safe for color-treated hair: maintains color while adding moisture.

How do I use the shampoo and conditioner for best results?

Apply the shampoo to wet hair, lather gently focusing on the scalp, then rinse thoroughly. Follow with the conditioner, distributing evenly through mid-lengths and ends, and leave on for 3–5 minutes before rinsing to maximize nourishment and detangling benefits.

• Step 1: Wet hair, apply shampoo, massage scalp for 60–90 seconds.
• Step 2: Rinse shampoo fully to remove residue.
• Step 3: Apply conditioner from mid-length to ends, leave 3–5 minutes.
• Step 4: Rinse and style as usual; use routinely for visible improvement.

Is this gentle enough for everyday use and sensitive scalps?

The formulation is sulfate-free and designed for frequent use, helping protect the hair’s natural oils and reduce dryness from over-washing. Those with specific scalp sensitivities should patch-test or consult a dermatologist if unsure, but many customers with normal to dry scalps find the set comfortable for regular routines.

• Sulfate-free cleansing reduces potential irritation from harsh detergents.
• Balanced rosemary extract supports a comfortable scalp feel.
• Suitable for most hair types, including color-treated hair.
• Patch test recommended for highly reactive scalps or allergies.
