Do FUE white dots get smaller over time? Mine look horrible 7 days out (Photos)

Based on your photos, that does NOT look like a 1mm punch.  Although most physicians tell you they are using 1mm, a lot may not.  In fact, the scarring I see on your photos is fairly bad and typical with what I see coming out of practices that don't have a clue what they are doing.While a 1mm punch sounds like a small punch size, when it comes to FUE hair transplantation, it's actually not the smallest. In fact, it's a larger size than is recommended by most experienced hair surgeons who are up-to-date with the latest research. At my office we use a 0.7mm punch with most cases. While FUE is known for being the procedure with the least visible scarring (compared to FUT/strip), it does still leave behind scarring. Generally, when the procedure is done correctly, the scarring is not very visible to the naked eye. But, when a larger punch size is used, such as 1mm, there is an increased risk for permanent visible scarring.  Additionally, the temples are not typically considered a safe and healthy donor area for graft extraction. I am curious as to why the doctor chose to do that. Also, it appears as if you has a high number of grafts extracted. We often refer to these procedures as 'mega-sessions' and these also carry with them an increased risk of visible scarring. I would urge you to thoroughly vet the doctor that performs your next repair procedure. 

FUE harvesting will lead small round scars that may look pale or white.  As your hair around the scar grows it should cover the white dots.

It's too early to start worrying- it usually takes a few weeks to a few months for the FUE scars to fade but they won't go away completely. It looks like your doctor may have taken from an area beyond the normal safe donor zone and the punch size was also a little larger than what most doctors use now- but I don't think you have anything to worry about assuming you manage your hair loss and your doctor has addressed this. 

It is too early to judge the final look of your donor areas within the first few days. We usually don't see many patients with hypo pigmentation any more due to the small size of punches we use today.  Our punches are 0.7-0.9mm in most cases that minimizes the visibility of the donor scars.

FUE is not "scarless" surgery, though the scarring is typically more subtle than with the FUT technique.  As the donor sites heal, they tend to contract and fade over a period of months (not days), and usually if your hair is a few millimeters long and if you have not been overharvested the sites are not visible.  Give it time and things should settle. 

The white dots reflect the shampoo absorption on the skin edge of the grafts and this will go away in a week or so once the recipient area is healed and the skin sheds. Your donor area extends will beyond what we call the Safe Donor Area. Assuming that you will not be very bald, this may not be a problem. I would advise that you discuss this with your doctor if your projected hair loss pattern would eventually become more advanced.        

the donor area goes through its healing process and it usually takes about a couple of weeks to heal. As for the scar from fue, in time the dots do shrink, but you may still see the small dots in the donor zone. 

FUE scars will fade over time but the size will stay the same and if you wear your hair very short you will still see scarring. Your picture at 1 week does not appear to show shock loss but donor area is beyond safe donor site and if not on Finasteride you should discuss it with your doctor.
