Although most hair coloring treatments are considered "safe" for transplanted hair, none of them are nourishing or good for transplanted hair. Unfortunately, when hair loss appears grey hair generally follows, but not all hair transplant patients are forced to accept grey hair. In fact, many hair restoration patients dye their hair regularly without any issues. In this article, we will discuss what causes hair loss and how long patients must wait before dying their hair.
What causes hair loss
There are various forms of hair loss, but the most common form is called androgenic alopecia or genetic hair loss. This form of hair loss is caused by an individuals genetic vulnerability to certain hormones that are produced by both men and women. The main hormone responsible for causing hair loss in men and women is called dihydrotestosterone (DHT), this hormone binds to the hair follicle receptor sites and essentially shrinks the hair follicle until it no longer grows.
How long should patients wait before dying their hair
There are several factors to consider before dying transplanted hair. First and foremost, patient's need to make sure they have allowed sufficient time for the recipient sites to heal and the follicular units to fully anchor in to their scalp. Generally, most patients heal quickly within the first 7-10 days following hair restoration surgery. However, most surgeons advise patients to wait a full 90 days before dying their hair, because some dyes carry harsh chemicals that could potentially harm the grafts if applied too soon. In addition, some patients may experience an allergic reaction when applying dye to their hair and scalp. Therefore, patients are advised to do a skin allergy test with the hair dye prior to applying the dye to their scalp to ensure there is no allergic reaction to the dye.
While most hair dyes are considered safe to use by hair transplant surgeons, most surgeons recommended patients stay away from hair dyes that contain harsh chemicals like peroxide and bleach. These harsh chemicals can severely dry out the hair follicle and cause them to become brittle and damaged. However, it is recommended to follow the physicians post-operative instructions and if it is not clearly indicated on the post-operative instructions; patients are advised to contact their surgeon directly.
