Hello Dr. Rassman,
I am writing to you from Turkey. As you know, in the eastern traditions and to a certain degree in the western traditions, homemade hair loss remedies such as oils, onion juice, vinegars etc. are used. Although it is clear that all these are not based on scientific grounds, is there any beneficent aspect of these?
Short answer — no. If these home “remedies” had any truth to them, you wouldn’t see too many balding men. Smearing your scalp with onions, vinegar, oils, lotions and potions are not going to regrow your hair.
