Is it Okay to Itch Your Head After Hair Transplants?

first 2-3 months it is normal that you have this kind of problems. İt will going to get normal with time. You don't have to worry about that.

Itching after hair transplant is very common, both at the donor and recipient areas.  Scratching should be avoided during the initial recovery period until all scabs and crusts are gone.  After all the scabs are gone (usually around the two week time frame), gentle scratching is probably not an issue, but should be avoided if possible to avoid traumatizing the scalp or causing infection.  There are topical treatments and oral medications that your hair transplant surgeon can offer and can be very helpful for itching if needed.
All the best,

Assuming you avoided scratching the transplant area for the first few weeks, some gentle scratching should be fine. At the 2-month mark, you're likely in between the initial shedding phase and the growth of new hair (which happens at about 3 to 4 months), and that can cause some itchiness. You may also want to ask at your local pharmacy about topical products that might help to add moisture and soothe your scalp. Hang in there!

After two months you should not have to worry about scratching your head.  If you are concerned, it is always a good idea to follow up with your doctor

By two months the follicles should be well integrated into the scalp.  Gentle scratching an itch shouldn't pose a problem.  Don't break the skin.  Mild itching is not uncommon. Extensive itchiness should be evaluated by your doctor.
