Shaving things such as pubes leg hair or armpit hair will grow back thicker but not necessarily darker because it just appears that way because its a new healthier hair but for other places like eyebrows and stomach that have thin hair or little hair shaving them can actually stop them from growing back in some cases -to stop hair from growing back thicker u would pluck or wax removing the hair root from its follicle and shaving this can rarely remove the hair root but shaving most of the time only trims the hair for a short period of time because you didn’t completely remove the hair root which causes the hair root to get stronger because you let it stay and absorb more nutrients from your skin and oils and that sometimes makes your hair thicker and healthier and newer giving the appearance of darker hair depending on the area you shaved but the only reason shaving makes hair stronger is because it is new healthy hair compared to when u never shave and leave old hair that over time dies and appears thin. But the hair root can usually make more healthier new hair if not constantly removed
