How to Use Neem Leaves for Scalp Infections & Hair Fall: 20 Proven Remedies That Work

Why Neem Works: Science Behind the Leaves

• Bioactive compounds
  Neem (Azadirachta indica) is packed with triterpenoids like azadirachtin, nimbin, and nimbidin—natural antifungal, antibacterial, anti-inflammatory, and antioxidant agents roshnibotanicals.com+15healthshots.com+15researchgate.net+15theestheticclinic.com+6en.wikipedia.org+6clinikally.com+6.

• Antifungal efficacy
  Neem leaf extract inhibits pathogens like Malassezia, Microsporum, Trichophyton, and Staphylococcus species—proven by powerful zones of inhibition and MIC values comparable to ketoconazole and fluconazole pmc.ncbi.nlm.nih.gov.

• Anti-inflammatory action
  Contains compounds shown to suppress nitric oxide production (iNOS) and inflammatory markers—at levels even superior to indomethacin in macrophage assays pmc.ncbi.nlm.nih.gov+1clinikally.com+1.

• Antioxidant & follicular support
  Rich in phenolics/flavonoids (rutin, rosmarinic acid) with ORAC, FRAP, and DPPH activity—protecting scalp cells and promoting healthy follicles self.com+6clinikally.com+6cityskinclinic.com+6pmc.ncbi.nlm.nih.gov.
