I've had a hair transplant done a couple of years ago, and for me, it was a game-changer. The procedure involved taking healthy hair follicles from the back of my head and transplanting them to areas where I was experiencing hair loss. It took a few months to see noticeable results, but the growth has been steady since then.
In terms of costs, it really varies depending on the location and the extent of the procedure. Mine cost around $5000, but I've heard of others paying more or less. One thing to keep in mind is that there can be some discomfort and downtime after the surgery, but for me, it was a small price to pay for the confidence boost I've gotten from having a fuller head of hair.
