Dr. Groot Hair Thickening Shampoo is a Korean-formulated, biotin-enriched shampoo designed to gently cleanse the scalp while adding visible volume and hydration to thinning, damaged, or color-treated hair.

Built around scalp-first care, this formula combines biotin, rosemary oil, caffeine and encapsulated prebiotics to remove buildup, moisturize, and lift hair at the root. The product is free from parabens, sulfates, silicones and gluten, and has been dermatologically tested and recognized in industry awards. Regular use aims to improve scalp condition and make hair appear fuller without harsh stripping.

How does this shampoo improve hair appearance without weighing hair down?

The shampoo targets the scalp to clear residue and add lightweight hydration, so strands don’t get coated with heavy oils or silicones. Ingredients like biotin support hair fiber resilience while rosemary oil and caffeine help invigorate the scalp environment, producing a noticeable lift from the base.

• Biotin: supports hair strand strength and resilience.
• Encapsulated prebiotics: remove buildup and balance the scalp surface.
• Lightweight moisturizers: hydrate without heavy residue.
• Sulfate- and silicone-free: preserves color and natural movement.

What results can I expect and how quickly might I notice changes?

Users and published studies report measurable scalp moisture and reduced buildup within a few weeks, with visual improvements in scalp redness from dryness noted in tested groups. Individual results vary by hair type and routine, but many people see better manageability and fuller-looking hair after several washes.

How should I use this shampoo for best results?
