5. Latest suggestions from experts (interview with the director of the dermatology department of a tertiary hospital)
1. If hair loss exceeds 100 strands per day and lasts for two weeks, you need to seek medical treatment. Simply taking vitamin supplements may delay the timing of treatment.
2. Vitamin absorption testing is more important than content testing. It is recommended to check digestive function at the same time.
3. Internet celebrity "hair growth vitamins" often contain excessive doses, so be careful about the burden on your liver and kidneys.
Conclusion:Although vitamin deficiency is a common cause of hair loss, it requires comprehensive management including sleep, stress, hormones, etc. New products such as "anti-hair loss gummies" and "hair growth coffee" that have been hot-selling recently lack clinical verification. Consumers are advised to choose rationally.
