I've been answering a lot of questions lately about smoking marijuana and the effects it can have on adrogenetic alopecia. Simply put, can marijuana cause hair loss?
Fortunetly not, but it can aggravate such medical conditions such as alopecia areata (bald spots on the scalp).
Smoking marijuana habitually can cause a general loss of hair through its effects on the liver, but since 2002, Evolution Hair Centers have never treated a client with hair loss directly related or steming from smoking marijuana.
