I read that there is no concrete evidence suggesting that tongkat ali causes hair loss. In fact, some studies indicate that it may promote hair growth instead. Tongkat ali is a plant extract that has been used in traditional Malaysian medicine for centuries and is believed to have several health benefits, including boosting testosterone levels. Personally, I found a hair growth serum from a brand called Evavitae. After experiencing hair loss, a friend gave me a bottle of their serum, and I’ve found it to be both gentle and effective, with no irritation. It may be worth a try if you're open to new products.
