I used to overpluck/shave my eyebrows and now they are thin, uneven & haven't regrown in some places. What can I do? (Photo)

Hello,
There are various methods to thicken eyebrows:
Latisse- off label use has reportedly helped some patientsEyebrow transplantation- We use follicle unit extraction FUE (off-label use of ARTAS) with regenerative techniques to ensure healthy looking browsMicroblading- Tattooing of the eyebrows which lasts between 6 months to a yearBest,

Over plucking hairs or eyebrows may lead to permanent hair loss.  If the hairs have not grown back in several months to years then it will never grow back.  Hair transplant surgery may be one solution.

You might consider Latisse which is a prescription eyelash enhancer.  Eyebrow transplants are difficult to make look natural.

From the sounds of it the prolonged period of over plucking your eyebrows might have caused permanent damage to the hair follicles. If you feel you have waited a sufficient amount of time and you still didn't see any growth in these areas this can mean the follicle itself has died and will no longer grow hair naturally. A hair transplant can definitely be an option for you if you have already tried other means of growth such as using Minoxidil. 

It seems that overstyling and shaving contibuted to the loss, but be sure to review all the details with a hair specialist so that an up close exam can be done.Hair transplants are an option but you might consider minoxidil or bimatoprost (Latisse) as a first step. These are not formally approved for eyebrows but countless numbers of patients have used these treatments with good results.You will know in 5-6 months if these help or not.

This will cause traction alopecia and the hair that is lost is lost forever. The best treatment for this is an eyebrow hair transplant and even better, stop plucking your eyebrows. 

If Latisse doesn't work , consider permanent makeup (tattooing). Eyebrow transplants can be considered after that.
