Fuller Hair. Stronger Strands. Built for Men.

Genesis Homme Thickening Shampoo is the premium daily hair care solution engineered specifically for men dealing with fine, thinning, or volume-deficient hair. Developed by Kérastase — one of the world's most respected professional hair care brands — Genesis Homme combines a gentle yet effective cleansing base with a targeted thickening and strengthening complex that visibly boosts volume, fortifies fragile strands, and helps reduce breakage from brushing and styling. Hair thinning in men is not simply a cosmetic concern — it reflects changes in the hair follicle's growth cycle, shaft diameter, and structural integrity that begin as early as the mid-20s and progressively worsen without proper scalp and hair care intervention. Genesis Homme addresses these concerns at the strand level with every wash, making it the smart, science-backed choice for men who want to get the most out of every hair they have — thicker-looking, fuller, stronger, and healthier from root to tip.

Key Benefits

• Visibly boosts volume and thickness for fine and thinning hair, creating the appearance of denser, fuller hair with every wash
• Strengthens hair fiber to reduce breakage from daily brushing, styling, and mechanical stress
• Gentle enough for daily use — cleanses effectively without stripping the scalp of essential moisture and oils
• Supports a healthy scalp environment that is foundational to optimal hair growth and retention
• Specifically formulated for men's hair texture and scalp needs, including oilier scalps and shorter hair styling patterns
• Professional-grade Kérastase formula trusted by stylists and hair care experts worldwide

Suggested Use

Apply to wet hair and scalp, lather generously, and massage thoroughly into the scalp using fingertips (not nails) to stimulate circulation and ensure full product contact with the scalp and hair roots. Leave on for 1–2 minutes to allow the active ingredients to work, then rinse thoroughly with lukewarm water. For best results, follow with Genesis Homme conditioner or mask to complement the thickening and strengthening benefits. Suitable for daily use. Avoid contact with eyes — rinse with water if contact occurs. For external use only.

Key Features

• Thickening Complex for Visible Volume: Genesis Homme's formula includes a targeted thickening complex that coats and plumps individual hair fibers from root to tip, increasing the visible diameter and body of each strand. This creates the cumulative effect of noticeably fuller, denser-looking hair — the kind of volume that makes a visible difference in overall hair appearance, particularly for men with naturally fine hair or hair that has become progressively finer with age
• Anti-Breakage Strengthening Technology: The Genesis line is built around Kérastase's proprietary anti-fall and strengthening technology, which works to reinforce the hair fiber's internal structure and surface integrity to reduce the mechanical breakage that causes hair to appear thinner over time. By minimizing daily hair loss from breakage during washing, detangling, and styling, Genesis Homme helps men retain more of the hair they have and maintain a fuller appearance over the long term
• Gentle Daily Cleansing Formula: Many thickening shampoos rely on heavy sulfate cleansers or coating agents that can build up on the scalp, clog follicles, or cause dryness and irritation over time. Genesis Homme's gentle cleansing base effectively removes excess sebum, product buildup, and environmental pollutants — all of which can compromise scalp health and hair follicle function — without disrupting the scalp's natural moisture balance, making it suitable for safe daily use
• Men's Scalp-Specific Formulation: Men's scalps produce more sebum than women's, are more prone to follicular buildup and scalp inflammation, and have distinct hair fiber characteristics that require a tailored approach. Genesis Homme is specifically formulated with these male scalp and hair biology considerations in mind — balancing effective oil control and deep cleansing with the thickening and strengthening benefits that address the unique pattern of hair thinning and volume loss most commonly experienced by men
