Other causes include autoimmune diseases and radiation therapy to the head. It’s important to note that some of these causes may be temporary or reversible with appropriate treatment, while others may lead to more permanent hair loss.
After the telogen phase, the hair follicle re-enters the anagen phase, and a new hair strand begins to grow, pushing out the old club hair. This process is part of the natural hair cycle, and it ensures that there is a constant turnover of hair on the scalp.
It’s important to note that the hair growth cycle is not synchronised across all hair follicles. This means that at any given time, some hair follicles are actively growing, while others are in the resting phase. This is why you typically don’t notice all of your hair falling out at once.
Various factors, including genetics, hormonal changes, and environmental influences, can influence the duration of each phase and the overall hair growth cycle. Understanding this cycle is important for understanding normal hair growth as well as conditions like hair loss (alopecia).
Finasteride is a medication used to treat male-pattern baldness (androgenetic alopecia) and an enlarged prostate (benign prostatic hyperplasia). It works by inhibiting the activity of an enzyme called 5a-Reductase.
By maintaining a lower level of DHT in the scalp, Finasteride helps to stabilise the hair loss process. In some cases, it may also promote the growth of thicker, healthier hair in areas that have experienced recent hair thinning.
It’s important to note that Finasteride is most effective for individuals experiencing hair loss due to elevated DHT levels (as in androgenetic alopecia). It may not be as effective for hair loss caused by other factors.
Remember, individual responses to Finasteride may vary, and not everyone will experience the same results or side effects.
