Hi this Vignesh, My son had severe dandruff problems for two years, starting when he was in 7th grade. Despite consulting various doctors, the dandruff was not cured. However, After my friend refilled the PaMee hair oil and using it consistently for about 6 months to a year, the dandruff completely disappeared. Now, their entire family uses it. Additionally, I have white hair, and after 6 months of use, 15-20% of the white hair has been removed, I truly recommend PaMee hair oil.
