Buying Guide – How to Choose the Right Hair Growth Solution

• Supplements vs Topicals: Supplements (Nutrafol, Viviscal) work internally but take 3–6 months; topicals (Rogaine) work faster on follicles but require consistent application.
• Gender-Specific: Choose Nutrafol Women/Postpartum or Viviscal Women; men with early loss may prefer Nutrafol Men or Rogaine.
• Instant Coverage: If you want immediate visual results, Toppik is a cosmetic quick fix.
• Hormonal & Stress-Related: Nutrafol Women or Postpartum are designed to address these triggers.
• Budget: Viviscal and Rogaine are generally more affordable long-term; Nutrafol is premium but highly researched.
