Quoted source text: "I think it is important to decide knowing what period of time you will have to go through."
Sensation becomes dulled
When touching the incision area or the scalp behind it, the skin may feel unfamiliar even though it is your own. Washing your hair can feel strange, and you may experience itching or tingling. These sensations often improve over time, but they can be bothersome during recovery.
Scars do remain
Forehead reduction involves an incision along the hairline, so it is not a surgery that leaves no scar. Initially the scar can be red and noticeable. Over time it fades and is hidden by hair, but you must wait for that to happen. In most cases it is not visible at conversational distance, and if the scar continues to bother you after time has passed, it can be covered with hair transplantation.
Endotain may be palpable
Endotain is an absorbable material that gradually disappears over time, but until then it may be felt or it may seem like the endotain is moving, which can feel unfamiliar. Using a mini endotain can reduce that sensation considerably.
Accompanying loss of nearby hair can occur
During surgery, surrounding hair can experience temporary shock, causing existing, non-operated hair to fall out. There is a period when the forehead is reduced yet the hairline looks sparse, which is when patients are most worried. Most of the hair regrows, but knowing and waiting for that fact is quite different from experiencing it without knowing. I don't want to describe this as merely a surgery that reduces the forehead by a few centimeters.
I think it's important to decide with an understanding of what time and process are required. Start by knowing not only how things might improve but also the process to get there. You should feel reassured during the process as well as with the result.
Bleeding, infection, widened scarring, sensory loss, asymmetry, accompanying loss of surrounding hair, less reduction than expected or re-elevation of the hairline may occur. Whether surgery is possible and the extent of reduction will be determined after examination.
