Pronexa Hairgenics Clinical Strength Hair Growth Shampoo — 8 fl oz, Biotin & Collagen for Thinning Hair

Pronexa Hairgenics Clinical Strength Shampoo is a professional-grade hair growth and regrowth formula that combines high-concentration biotin, collagen, and scalp-supporting actives to help reduce thinning and strengthen hair strands.

This sulfate-free shampoo is formulated to target the visible signs of thinning by nourishing the scalp, fortifying fragile shafts, and supporting a healthier hair growth cycle. Designed for daily use and safe on color-treated hair, the Pronexa Hairgenics formula blends metabolic boosters, botanical extracts, and DHT-targeting ingredients to create a more resilient, fuller-looking mane over time.

How does this shampoo help with thinning hair?

Pronexa works on multiple fronts: it supplies biotin and vitamin B5 to support follicle metabolism, uses collagen to strengthen the hair fiber, and includes botanicals that improve scalp circulation. These combined actions help existing hairs resist breakage and encourage follicles to re-enter an active growth phase.

• High-concentration biotin and vitamin B5 to energize follicles
• Collagen to reinforce the hair shaft and reduce snapping
• Botanical blend to enhance scalp micro-circulation and nutrient delivery

What makes this a clinical-strength formula?

Clinical-strength refers to the concentrated actives and a targeted delivery approach intended for advanced thinning concerns. Pronexa is made in a GMP-certified facility and formulated with potency and stability in mind so active ingredients remain effective with regular use.

• High-dose biotin complex for metabolic support
• Stabilized collagen for structural repair of strands
• Manufactured and tested in a GMP-certified U.S. facility

Can I use Pronexa on colored or chemically treated hair?

Yes — the shampoo is engineered to be gentle while delivering performance ingredients, making it suitable for daily use on color-treated and chemically processed hair. Its mild cleansing base removes impurities without stripping color or essential moisture.

• Safe for color-treated and chemically processed hair
• Gentle enough for daily cleansing routines
• Helps prevent breakage that can worsen visible thinning

How soon will I see results and how should I use it?

Visible improvements depend on individual hair cycles and consistency of use. For many, increased manageability and reduced breakage appear within weeks; fuller-looking density requires regular use over several months. Follow a routine of massaging into scalp, leaving for 1–2 minutes, then rinsing thoroughly.

• Massage into wet scalp and hair, leave 1–2 minutes, then rinse
• Use daily for best results; consistent application is essential
• Combine with a balanced haircare routine for optimal outcomes
