Why do alcohol and smoking cause hair loss?
Smoking, on the other hand, is harmful to the hair due to the chemicals in cigarette smoke, such as carbon monoxide, that can reduce the amount of oxygen available to the hair follicles. This lack of oxygen can weaken the hair and make it more susceptible to breakage. Additionally, smoking can cause oxidative stress and inflammation in the scalp, weakening the hair shaft and making it more prone to breakage.
Finasteride is a prescription medication commonly used to treat hair loss. It works by blocking the production of DHT, effectively reducing the hormone's negative impact on hair growth. Finasteride is highly effective in reducing hair loss and promoting hair growth and is considered one of the best DHT blockers available. However, as it requires a prescription, it should only be taken with medical supervision.
In summary, alcohol and smoking can lead to hair loss by affecting the hair's ability to receive the nutrients and oxygen it needs to grow and remain healthy. To maintain healthy hair, reducing or quitting drinking and smoking is crucial, as adopting habits that support hair growth, such as eating a balanced diet, getting enough sleep, and reducing stress.
