Archives for FUE VS STRIP

A comparison between strip harvesting and FUE hair transplants

In strip harvesting, doctors take strips of hair-bearing tissue from part of the head and place them elsewhere, while with FUE – follicular unit extraction, doctors take follicular units of one to four hairs instead of entire strips, and transplant them elsewhere on the head. 

In this second article of the three-part series we will talk about graft survival, graft placement and graft numbers. 

Graft Survival

Debate exists over the rate of survival using FUE versus strip grafts. There is some concern that since FUE grafts may have very little tissue surrounding them, they are less likely to survive. Such grafts are more prone to dehydration, which has been shown to be a major cause of diminished graft survival. The lack of tissue surrounding the hair follicle is often a result of “pulling” on the graft to remove it. Because there is added manipulation in trying to remove a graft this may also contribute to diminished survival.

With FUE hair transplants there is a greater chance of damaging hairs as compared to strip harvesting, and this could result in poor growth or lack of growth depending on the level of damage. The rates of damage seem to vary widely with FUE. Conversely, with strip harvesting, grafts may be damaged in making the initial skin incisions and subsequent dissection of the tissue, but this is considered minimal. The use of the microscope for dissection of the donor strip should limit damage rates to 1-2{acd4a358aa854be283d148c7810f1013831bd5d6bf73206c5f743beae9259ccd}. Grafts created with strip harvesting generally have a greater amount of surrounding tissue and fat. This may decrease the chance of dehydration and allow for greater leeway in manipulation of the grafts during placing and hence, better graft survival.

Placing of Grafts

When manual placement of grafts is used there is no difference between the two techniques. There may be some concern about the fragility of FUE grafts and the fact that they may be more susceptible to drying.

Perfectly harvested grafts may be damaged during the placement phase and fail to grow. Trauma and graft drying are well known factors that may occur in inexperienced hands and will impact graft survival. Regardless of how grafts are harvested, there is a considerable amount of artistry and technical expertise necessary to place them to produce an excellent or even acceptable result. The surgeon must be able to create an aesthetic “blueprint” for graft placement, determining the distribution of 1, 2, and 3 hair grafts. Hairline design is obviously important, as is the grafting plan over the rest of the scalp.

Number of grafts per session

In general most physicians who perform FUE hair transplants cannot do as many grafts in a single session they can with strip harvesting. With strip harvesting, sessions of 2000-3000 grafts are very common and some physicians frequently perform sessions in excess of 4000 grafts. There are, however, exceptions and some physicians, routinely performing FUE, report similar in excess of 2000 grafts.

Some patients are turning to Low-Level Laser Therapy Devices as a non-surgical hair restoration treatment for pattern hair loss.

These devices, which feature laser light generated by low-powered cold lasers, include hand-held “comb”, “brush” or “cap” laser-fueled devices marketed for use at home. Larger “hood” or “cap” devices are used in hair restoration clinics.

Laser light is not approved or recommended for treatment of hair loss due to any other cause. If the cause of hair loss is questionable, you should see a physician hair restoration specialist for appropriate diagnosis before using a LLLT product.

The “cold” lasers used as a hair replacement therapy for the treatment of pattern baldness deliver what is called low-level laser therapy (LLLT). The LLLT lasers are called “cold” because their light is absorbed by target tissue, but does not heat the target tissue as occurs with lasers used to cut and remodel tissue.

Here we will outline some of the home LLLT devices available for your usage.

LLLT Devices

Hand-held LLLT devices for home use that are currently marketed on the World Wide Web and by advertising in print media include:

The HairMax LaserComb: It has comb teeth and embedded lasers that deliver laser light to the scalp as the comb teeth part the hair. The HairMax Laser Comb has been cleared by the U.S. Food and Drug Administration (FDA) for marketing as a device to treat pattern hair loss. The HairMax Laser Comb is available by direct order or from a physician’s office. The cost of a HairMax Laser Comb is several hundred dollars.

The X5 Laser: This uses laser diodes to deliver light directly to the scalp. It is marketed as a cosmetic device and needs no additional FDA clearance for that use. The X5 Laser is sold for about $200.

The Laser Cap: This uses 224 lasers embedded in a wearable hat. It is available through physician offices, is marketed as a cosmetic device and needs no additional FDA clearance for that use. The Laser Cap is sold for about $3000.

The potential consumer should compare hand-held devices not only for price, but also for features such as scalp coverage and power.

LLLT devices used in a medical clinic are hoods much like a beauty salon hair dryer.

The effectiveness and most advantageous use of LLLT for hair restoration has not yet been investigated in large, long-term, well-designed clinical trials.

The ISHRS takes no official stand on LLLT as a treatment for hair loss. On the one hand, it recognizes that some members strongly believe in LLLT as a complement to other treatments. On the other hand, the ISHRS is aware that there is currently a lack of good support from large, well-designed double-blind studies to support the effectiveness of LLLT as a treatment for hair loss. Some ISHRS member physicians believe that this lack of evidence should make us cautious about recommending LLLT to our patients until more scientific studies are performed.

In summary, LLLT may be an appropriate treatment for some patients with male or female pattern hair loss. Patients should discuss this option with a qualified physician hair restoration specialist.
