It's a procedure that involves creating small incisions in the scalp and carefully placing hair follicles from a donor area into the designated transplant area. The success of the procedure depends on how well the channels for transplanting the hair are prepared.
Two main factors are crucial in the channel opening process: size and depth. The channels need to be just the right size for the hair follicles to avoid damaging them during implantation. If the channel is too small, it could harm the root, and if it's too large, it may lead to tissue damage and scarring. The depth of the channel is also important; it should be deep enough to protect the blood vessels that nourish the transplanted hair, but not too shallow as to hinder the follicle's growth.
During the channel opening process, several key points are considered:
1. Natural Appearance: The channels are opened in a way that aligns with the person's existing hairline to maintain a natural look.
2. Blood Circulation: Care is taken to avoid disrupting or damaging the blood circulation in the scalp while opening the channels.
3. Hair Growth Direction: The channels follow the natural direction of hair growth to ensure a more natural outcome.
4. Planting Frequency: The channels are opened based on the frequency of hair transplantation needed, and the number of hair roots to be implanted is also taken into account.
