Frequently Asked Questions

Can shampoo actually help with hair loss?
Topical shampoos won't reverse genetic hair loss, but they can significantly reduce hair fall caused by scalp inflammation, buildup, weakness, and breakage. They also improve the scalp environment for healthy growth.
What ingredients should I look for in thinning hair products?
Look for: caffeine (stimulates follicles), niacinamide (improves scalp circulation), biotin (strengthens structure), salicylic acid (removes scalp buildup), and keratin (reduces breakage). Avoid heavy silicones that smother follicles.
Is thinning hair the same as hair loss?
Not exactly. Thinning refers to reduced hair diameter (fine hair), while hair loss means reduced follicle count. Both can happen together. Thickening products help with the appearance of density; hair loss treatments target the follicle itself.
How long before I see results from thinning hair products?
Most topical treatments take 3–6 months of consistent use before visible results. Hair growth cycles are long, and it takes time for weakened follicles to produce thicker, healthier strands.

Why Buy From ProHair?

We carry clinical-grade densifying systems from L'Oréal Serioxyl and Nioxin — lines developed specifically around the biology of thinning hair, not generic volume claims.
