Highbrow Hippie Root Replenish scalp serum 40mL — lightweight water-based formula for thicker-looking, fuller hair

Root Replenish is a lightweight, water-based scalp serum from Highbrow Hippie formulated with Redensyl, DHT-blocking botanicals and fermented Resveratrol to support thicker-looking, denser hair when used consistently.

Designed to absorb quickly without greasiness, this 40mL serum targets the scalp environment using microbiome-supporting nutrients and plant-derived DHT blockers such as saw palmetto and green tea extract. It layers easily into daily routines and is cruelty-free and water-based, built to soothe, strengthen roots, and help hair appear fuller over time when applied as directed.

How does Root Replenish support fuller-looking hair?

The formula combines clinically-supported actives and botanicals that focus on root strength and scalp balance rather than promising miraculous regrowth. Ingredients like Redensyl and fermented Resveratrol work alongside DHT-blocking extracts to create a healthier scalp environment that can encourage the appearance of denser hair with regular use.

• Redensyl targets hair follicle stem cells to support thicker-feeling strands.
• Saw palmetto and green tea act as plant-derived DHT modulators.
• Fermented Resveratrol delivers antioxidant support to protect scalp tissue.
• Water-based, fast-absorbing texture leaves no oily residue.

What does it do for scalp health and microbiome balance?

Root Replenish emphasizes scalp ecosystem support by combining microbiome-friendly nutrients with anti-inflammatory botanicals. That combination helps neutralize environmental stressors and soothe the skin of the scalp so it can better support hair at the root level.

• Prebiotic-style nutrients to help maintain a balanced scalp microbiome.
• Ingredients chosen to calm inflammation and reduce irritation.
• Antioxidant-rich actives protect against environmental damage.
• Non-greasy delivery allows daily use without buildup.

How should I apply the serum for best results?

Apply a thin layer directly to the scalp and gently massage for about 30 seconds to promote absorption and circulation. Use twice daily—morning and evening—or as a targeted spot treatment; consistency over weeks is key for visible changes in hair thickness and density.

• Apply to clean, dry or towel-dried scalp twice daily.
• Massage gently for 30 seconds to aid absorption and stimulate circulation.
• Use spot treatment or distribute across thinning areas as needed.
• Pair with Highbrow Hippie Essential Wellbeing Complex for complementary support.

Which ingredients are highlighted and why should I care?

The serum blends plant-based DHT blockers like saw palmetto with green tea extract, plus Redensyl for follicle support and fermented Resveratrol for antioxidant protection. The choice of water-based, clean ingredients limits residue and enhances layering within existing styling or care routines.

• Saw palmetto and green tea: plant-derived DHT support.
• Redensyl: targets follicle cellular activity linked to thickness.
• Fermented Resveratrol: antioxidant and scalp-protective benefits.
• Prickly pear and other botanicals: nourishing, non-greasy hydration.

Who is this for? Root Replenish suits adults seeking a clean, plant-forward serum to improve the look of hair density and scalp comfort—especially those noticing thinning, increased shedding, or wanting to proactively support scalp health. It works well for all hair types since the lightweight, water-based formula absorbs quickly and layers with other styling or treatment products.
