OGX ProGrowth + Peptide Scalp Serum for Thinning Hair, 0.33 fl oz — Peptides & Caffeine for Fuller-Looking Roots

OGX ProGrowth + Peptide Scalp Serum is a lightweight, click-pen treatment formulated with peptides, caffeine, and micro-algae to help strengthen roots and support visibly fuller-looking hair when used daily.

This water-based serum was developed with trichologists to target fine, thinning, or damage-prone hair. The formula combines a 9% Long7vity Complex and scalp-support ingredients like niacinamide, feverfew, vitamin B5, and mango extract to nourish the scalp and roots without heavy oils or alcohol. Packaged in a precision click pen, the serum delivers targeted drops to the scalp for an easy, mess-free application that fits into morning or nighttime routines.

How quickly can I expect to notice fuller-looking hair?

Visible improvements were observed in consumer and instrumental studies within about 30 days when the serum is used as directed alongside the complementary shampoo and conditioner. Individual results vary, and consistent daily use is important for best effect.

• Designed to be used once daily, 3–6 drops applied to the Scalp T-Zone.
• One pen typically lasts up to 30 days with recommended use.
• Best combined with OGX ProGrowth + Peptide shampoo and conditioner for fuller-looking results.

What key ingredients are in the formula and what do they do?

The serum centers on a 9% Long7vity Complex made up of peptides, caffeine, and micro-algae to support root reinforcement. Additional scalp-focused actives — niacinamide, feverfew, vitamin B5, and mango extract — help condition and comfort the scalp while promoting an environment that supports healthy-looking hair.

• Peptides: help reinforce hair at the root level.
• Caffeine and micro-algae: energize the scalp area and support a denser appearance.
• Niacinamide, vitamin B5, feverfew, mango extract: hydrate and soothe the scalp surface.

How do I apply the OGX ProGrowth scalp serum for best results?

Use the precision click pen once daily on clean, damp hair or on dry hair between washes. Focus 3–6 drops along the Scalp T-Zone — temples, part line, and front hairline — then gently massage with fingertips; do not rinse out to allow the lightweight, water-based serum to absorb.

• Click applicator dispenses small, controlled drops directly at the root.
• Massage briefly to distribute serum across the targeted scalp area.
• For routine maintenance, follow with styling or leave as-is; safe on color-treated hair.

Is this serum gentle enough for sensitive or color-treated hair?

The formula avoids alcohol, parabens, sulfated surfactants, and added fragrance, making it milder than many leave-on treatments. Its lightweight, water-based texture reduces buildup risk and is intended for daily use on fine, color-treated, or texture-diverse hair like curls and coils.

• Free from fragrance, parabens, sulfur surfactants, and alcohol.
• Fast-absorbing and non-greasy for everyday application.
• Appropriate for color-treated hair and varied textures when used as directed.

Who is this for: OGX ProGrowth + Peptide Scalp Serum is aimed at people with fine, thinning, or breakage-prone hair who want a simple, targeted leave-on treatment to support visibly fuller-looking hair. It’s a good choice for those seeking a lightweight, non-greasy option compatible with color-treated hair and who prefer a precise applicator for focused scalp care. If you want an easy daily step to reinforce roots and maintain scalp comfort while using a formulated routine, this serum fits into most haircare regimens.
