Does wearing a hat after hair trasnplant affects the hair?

You can wear a hat the day of the transplant if you like.  I would not wear a beanie.  I would use a regular hat that does not touch or move the grafts.  A loose fitting bandana or scarf will work too.  After the 6th day, you can generally wear any type of hat you like.  There are two things you are trying to prevent after a transplant.  One is to physically remove the graft.  The second is to move the graft because the circulation to the graft is reestablishing.  Once the graft is seated, you cannot remove it.  Most recommend 10 days, but one study showed that after the 6th day, grafts cannot be removed.  Good luck.  One month after surgery should not have created any negative consequences.  

We regularly encourage patients to wear a hat at the appropriate time after surgery. For patients having grafts to the hairline, top or crown of the scalp, a hat can be worn immediately after surgery.
For those also having grafts placed in the temporal points (those are the side borders of the forehead), we generally say to wait 5-6 days before wearing a hat so that the brim does not rub, dislodge or damage any of the temporal points' grafts.
Additionally, the scalp needs to be protect from sun & UV exposure for up to 6 months after your procedure, so wearing a cap of some kind will be a normal part of the longterm recovery and care of the scalp.
Hope that helps!

Dear albaajetiThanks for the question. Your grafts become safe during the 3-6th day after hair transplant. If you don´t harm or damage your scabs during that time, your grafts will be safe. You can start wearing a cap and put it on with caution already 1-2 days after hair transplant. I wish you all the best.

After hair transplantation, most patients can wear a hat somewhat safely 10 days.  This is because the hair grafts have taken root. Typically, I have patients wear a hat one month after surgery, especially loose fitting ones.  Physical contact of the grafts within a week can disrupt their growth.  Best Dr. Anil Shah 

Hello, Thank you for your question. Loose hats do not have any bad effect to hair transplanted area on the other hand they help to protect the area. I usually recommend my patients to wear a loose hat (fisher hat) immediately after the operation. Especially in the first week, protecting transplanted area against the sun and other external factors is very important. You could use hard hat or motorcycle helmets after first month.

Wearing a hat does not affect hair loss or the long-term viability of transplanted hair. Hats should only be very carefully worn in the first week or two post-transplant in order to avoid traumatizing or disrupting the newly transplanted grafts, but do not affect the long-term hair transplant result.
All the best,
