Is there anything I should avoid doing after hair transplant surgery after it grows in?
Sun Exposure – Protect the transplanted scalp from the sun for two or more weeks, either with a hat or SPF 45 sunscreen spray when outdoors for more than 5 – 10 minutes. This is to prevent forming dark spots on the healing skin. As is always true, sun exposure after this time should be judicious and use of sunscreen is always advisable as good health practice.
Exercise and Sports – There are no restrictions. You can swim, run, do aerobics, weight lifting, and even contact sports without fear of damaging your hair restoration procedure.
Sexual Activity – There are No Restrictions
