How is a Hair transplant surgery done
- There are two techniques available for hair restoration.
- Hair transplant using follicles from a strip of hair removed obviously from the back (Strip Method).
- Follicular Units that are extracted using devices from back (Follicular Units Extraction or FUT).
What is a Follicular Unit ?Just like trees have multiple roots and branches hair follicles can have multiple roots but one root produces only one hair, however each follicle is an individual entity and it must be preserved as such when dissecting it from a strip, hence we have Folliculr Units which may have one, two, or three roots and they produce one two or three hair respectively, an average scalp has about 50 percent of follicles which are double and rest of 50 percent is made of singles and 3s, predominantly singles.
Follicular Unit Hair Transplant with a strip.Advantages of this technique is that up to 3000 to 4000 grafts are available in a single sitting which can restore large areas with good density in first sitting itself, a strip of hair contains hair roots and skin which is removed from the back of scalp, and the resultant gap is then sutured to close the gap in the skin from where the strip has need removed, at our clinic we use video microscopes to dissect this strip into individual Follicular Units, which may contain 1,2 ,or 3 hair roots ,these follicles are then transplanted into front making small slits from 0.7 mm to 1mm in size to fit in these follicles at an average density of 35 to 40 follicles per square centimeter.The hair growth from this technique is better compared to extraction, as more stem cells are preserved around the follicles, when cut properly and inserted into the slits made with out damaging the grafts. A large number of grafts are available for transplant compared to follicular unit extraction technique.
