Hello. I have thin hair for the last 6-7 years and if hair not washed with shampoo I suffer from dandruff. Also since last 1 year my hair has become less in density. I tried using castor oil for 2 months or so. Shaved my head 4-5 times. But I can't see some effect. Now I was thinking to use apple cider vinegar to apply on my hairs. Is it ok? If yes. What brand should I use? Or any other natural remedies or ayurvedic remedies? FYI- My diet is well balanced. I workout as well.
