Dr. Groot Hair Thickening Conditioner for Thinning Hair — Biotin Formula, Reduces Breakage & Controls Oil

Dr. Groot Hair Thickening Conditioner is a biotin-enriched Korean conditioner formulated to visibly thicken strands, reduce breakage-related hair loss, and control scalp oil for fuller-feeling hair.

Designed as a daily hair-care step, this conditioner combines a protein-rich cream base with biotin, encapsulated prebiotics, rosemary capsules and scalp-supporting actives to improve texture, reduce sebum and strengthen fragile hair. Dermatologically tested and safe for color-treated hair, the formula avoids parabens, silicones, sulfates and gluten while aiming to leave hair softer, thicker-looking and less prone to breakage.

How quickly can I expect to notice reduced breakage or less hair coming out?

Clinical testing of the formula shows measurable improvements in a short time frame for breakage-related shedding. Users report reduced hair loss from breakage within two weeks, along with improved softness and scalp oil reduction after the first use.

• Clinical data: up to 82.2% reduction in breakage-related hair loss in 2 weeks*
• Instant effects: sebum reduction and improved manageability after one application
• Progressive strengthening: proteins and biotin work over repeated use to fortify strands

What key ingredients are in this conditioner and what do they do?

The formula blends performance-focused actives that address both hair fiber and scalp environment. Biotin and protein help reinforce the hair shaft, while salicylic acid and encapsulated prebiotics support a cleaner, balanced scalp. Soothing and energizing extracts complete the mix for healthier-looking hair.

• Biotin and protein cream base: strengthens and thickens individual strands
• Rosemary capsules and caffeine: nourish hair and invigorate the scalp
• Salicylic acid, niacinamide, panthenol: exfoliate, hydrate and improve scalp condition

Will this conditioner weigh my hair down or strip color-treated hair?

The conditioner is formulated to boost volume without heavy silicones that can leave residue. It is dermatologist-tested and labeled safe for color-treated hair, preserving dye while improving texture and hydration. The lightweight protein base aims to leave hair full and soft rather than flat.

• Silicone-free formula to avoid buildup and maintain natural lift
• Dermatologically tested and suitable for color-treated hair
• Formulated without sulfates or parabens for gentler cleansing compatibility

How should I use the conditioner for best results?

Apply after shampooing to clean, towel-dried hair, focusing on mid-lengths and ends while lightly massaging the scalp to distribute rosemary capsules. Leave on according to product directions, then rinse thoroughly. For consistent improvement in thickness and breakage reduction, use as part of a regular hair-care routine.

• Use after shampooing on damp hair, concentrate on lengths and ends
• Massage briefly to help capsules release botanicals, then rinse well
• For optimal benefits, include in routine with compatible shampoo and avoid heavy styling products
