Yes, alcohol can cause hair loss. If you are drinking alcohol, it can take the nutrients out of your system. So when you're drinking alcohol, you want to have something in your stomach. Many people are consuming their calories through alcohol. If you are drinking pina coladas or margaritas you could feel full because those drinks have sugar and many calories.
Alcohol can increase the acid in the system and destroy the lining of the stomach. It dehydrates us because it is pulling the water out of our system. It is also going to make sure that you do not detoxify as much. The other thing is sleep, if I have more than a glass, I will wake up all through the night. If you do not sleep, your body does not regenerate and repair, including your hair follicles.
Another crazy one is that alcohol affects estrogen levels. It can increase them. Estrogen, progesterone, testosterone, they are all doing this dance of balance. Alcohol affects estrogen levels. Estrogen levels affect other hormone levels, including dihydroxy testosterone, DHT, which can cause hair loss. Alcohol takes the B vitamins out of your system and absorbs them, particularly B1. What is the solution? The solution is not to drink excessively.
