I heard the tern “Donor Recharging“, what does it means?

CIT donor recharging is a method of preparation where each extracted scalp follicular unit is replaced with a body hair follicular unit. The exchange of these grafts isn’t always one for one but the purpose of CIT donor recharging is to replete the donor area and help the donor area from being too thinned from harvesting with hair transplant. CIT donor recharging also stimulates the production of melanin, a pigment in the donor area. Donor recharging allows patients with higher degrees of hair loss to maximize their scalp hair donor supply and fill-in the absence of extracted follicular units. The results with donor recharging are subject to the same limitations as BHT and results cannot be guaranteed. CIT donor recharging results vary from patient to patient and the appearance of the results is unpredictable.

When and how does the new hair grow in after my hair transplant ?

Many people ask this question during and after their hair transplant; some actually think the hair will all continue to grow and they will have their “new head of hair” immediately. Unfortunately, most individuals have to accept delayed gratification as part of the transplant experience!

When the grafts are placed in the balding areas, they indeed may continue to grow for a few weeks. However, by about three weeks, the hairs begin to rapidly shed and soon most all of them are gone. The good news is that the follicle cells, the ones that make the new hair shaft that grows up and out, are still lying dormant under the skin.

At about three to four months, the first hairs begin to sprout through the scalp. At first, all new hairs will be finer, and slightly less pigmented than they will eventually be after some growth time. It is important to note that the grafted hairs do not all begin to come in simultaneously; they generally sprout in a “staggered” fashion, which means that each month some new sprouts will be noticed emerging from the scalp, until they all have grown in! Full growth will have occurred, on average, after about 10 to 12 months; full ingrowth may sometimes take a little longer on second and subsequent procedures.

Of course, the full cosmetic effect may not be apparent right away. This is because length and caliber of hair, as well as density, contribute to coverage. Once the hair has grown long enough and each shaft has become thick enough, then the full coverage will be apparent and the welcome decrease in the appearance of thinning and baldness will be noticeable.

What is the importance of hair characteristics in hair transplant surgery?

These characteristics are significant in that they determine to a great degree how much coverage of the scalp there is, in order to block light. When light is not blocked and penetrates through to the scalp, the appearance is of thinning or balding.

The other big factor here is the density, which is another topic unto itself. The density is the number of hairs or follicular units per unit area (square centimeters or square inches or whatever unit you prefer; the centimeter is the standard for physicians). Although this density usually gets most of the attention when discussing hair loss, hair characteristics are equally, if not more, important.

First let’s look at color. At first, one might think that the darker the hair, the better the coverage. This is generally not correct. Lighter hair usually goes with lighter skin, and the tow together tend to mask thinning very well. Darker hair can cover well, but in the case of poor hair transplant work (pluggy looking, or larger graft on frontal hairline) they may stand out much worse than lighter hair. We will discuss color in more detail when we discuss contrast.

Curl is another very important factor in coverage. Generally speaking, curly hair provides coverage in proportion to the degree of curl (i.e., wavy hair gives better coverage than straight hair, curly hair better than wavy, very curly better than slightly curly, etc.). This has to do with light blockage as well. The curlier the hair is, the more it creates a meshwork of sorts (kind of like a thatched roof) which “stands up” a little bit off the scalp and keeps the light from penetrating to the scalp.

Contrast has to do with the difference between hair color and skin color. The closer to each other the hair and scalp are, the better the coverage. In a way, this “fools” the eye of the observer into not noticing the decrease in density. If a person with blonde hair and light skin loses 50% or his or her density, they may appear much less affected than a person with equally light skin and jet black hair. In this case the dark hairs of the second example are highlighted against the light skin and it shows the sparseness of the hair. The person with the blonde hair reveals very little difference between the hair and scalp, in other words, the observer cannot detect where the hair leaves off and the scalp begins.

Last, let’s consider caliber. Thicker strands of hair provide more “hair mass”, which is a term doctors use to describe the total effect of length times caliber. The more hair mass in a given area, the better the coverage. This makes intuitive sense. Imagine covering a hut with logs. If you place 20 logs as a roof, which will give better coverage, skinny logs or big round ones with large diameters? Of course, the bigger ones, so the thicker hairs do the same over the scalp. And remember, what appears as thinning or balding is simply the appearance of light shining through to the scalp.

What is Maximum Medical therapy for hair loss?

People with hair loss, and certainly anyone even CONSIDERING hair transplant, may want to use a regimen of maximum medical therapy. This just means using a number of different medications that have different mechanisms of action to try to “cover all the bases”, so to speak. Attacking hair loss by targeting different aspects of the process is a way of using the synergy between various agents to maximize the effects.

Finasteride (Propecia and Proscar) is an agent that blocks the formation of dihydrotestosterone (DHT), a hormone that has been implicated in male pattern baldness (androgenic alopecia). This is a first line drug for men with thinning hair or balding. It is not beneficial for women; in fact, it can cause birth defects if a woman is exposed to the drug and gets pregnant. It has few side effects in men and has been used for about 25 years with a good safety record.

Minoxidil (Rogaine and many generic versions) is topical, or placed directly on the scalp. Side effects are few, and it has a synergy when used with finasteride. This may be used in men and women, and is considered by many to be the drug of choice in women with hair loss.

There is some evidence that an anti-fungal shampoo containing ketoconozol (Nizoral) may help slow hair loss. It can be used twice a week and has the added effect of decreasing dandruff and itching of the scalp. There are also a variety of over the counter preparations (Hair Cycle products) and internet-marketed preparations that are available. Many of these contain minoxidil and other ingredients. Some of these are topical androgen (male hormone) blockers; there is little scientific proof of their effectiveness, but many men swear by them, and they may work for some.

The most important thing one can do with these latter agents is read and read some more. Information from sources other than the manufacturers is likely to be more objective and may help one with informed decisions.

It is really unknown what causes shock loss.  Shock loss is hair loss resulting from a hair transplant procedure.  There are many theories, however.  Shock loss most likely is due to an inflammatory response as a result of physical trauma.  It is really quite uncommon in the donor area.  It is more common in the recipient area.  The density of incision sites may play a role as high density incision sites tend to produce shock loss more commonly.  Shock loss will occur only in the area where the incisions are made.  It will not occur in adjacent regions.

Shock loss begins about 2 to 3 weeks after a procedure and it will continue over a period of a few weeks.  If you experience hair loss months after a procedure, it is not due to shock loss, but rather due to progression of hair loss or some other factor unrelated to the hair transplant procedure.

Some feel it is due to the injection of epinephrine, which is commonly added to the anesthetic.  This is most likely untrue as you will not see shock loss in areas where anesthesia is given, but rather only in areas where the incision sites were made.  You also more commonly see it in the recipient area while epinephrine is also given in the anesthetic given in the donor area during a hair transplant surgery.  Even though the same anesthetic with epinephrine is given in the donor area, you do not see shock loss in the donor area when it occurs in the recipient area.

The inflammation might result from physical trauma, but it also might be due to the free radicals that accumulate in tissue that continues to metabolize outside the body in an anaerobic state.  Free radical scavengers in the storage fluid along with cooling of the tissue outside the body might help reduce the amount of free radicals produced by the grafts.  One might also limit the free radical load by limiting the recipient area density during a hair transplant.

Shock loss is uncommon in the donor area with both strip harvesting and with FUE or FIT.

When shock loss occurs, the hair will generally begin to grow back after a hiatus of 3 months.  It is only the fine wispy baby like hair that seems most prone to remain dormant following shock loss.  This sort of baby fine, short, lightly pigmented hair produces the least amount of coverage, however, so it will not be missed as coarser, darker, longer terminal hairs will take their place when the hair transplantation produces new hair growth beginning three months after the hair transplant.
