When the hair growth product works, it stimulates hair follicles, causing the hair to enter into anagen or growth phase. As the hair follicles adjust to the new growth phase, they may temporarily shed the existing hair. This can lead to a sudden and noticeable increase in hair loss (shedding), which can be alarming for those who are using the medication.
Fortunately, shedding is usually a temporary phase that lasts for a few weeks to a few months. The hair follicles then adjust to the new growth phase, and new hair growth may begin.
It’s important to note that not everyone who responds the product positively will experience shedding, and the extent and duration of shedding can vary from person to person.
