Baldness problem in males, why choose the HST technique – graft with capillary multiplication, compared to other techniques.


Today, patients who suffer of alopecia often have two options for intervention: either FUT, also called strip, or FUE. The first consists of the removal, quite painful, especially in the post-operative phase, of a strip of the scalp of the occipital donor area.

This strip is thoroughly decomposed and each follicular unit obtained separately is transplanted into the recipient area. The suture on both sides of the wound created by the ablation creates a long scar that is really unsightly. With the second technique, FUE, the surgeon extracts each follicular unit separately and completely, then transplants it into the recipient area. Extracting the follicular units, create an empty small area that will heal by a possible hardening of the entire collection area.

FUT and FUE: the two techniques only move the follicular units

The common feature of the two techniques, beyond the mode of collection, is that they only transport available follicular units from the donor to the recipient area, and their limit consists of two factors: the number of follicular units available for sampling and the size of the area to be restored.

In the case of extensive alopecia, the follicular units are never sufficient, and therefore two negative cases present to the patient: the donor area is completely devastated with extremely important extractions, and the restoration will still be incomplete without hope of being able to complete the work, due to the depletion of the donor area. Unfortunately, many patients’ dreams are broken, because so many promises are not achievable. The most painful thing is that after having exhausted all the capacity of the donor area, unfortunately without satisfactory results, the patient must resign himself to not being able to dream of a correct restoration.

Dr Gho’s scientific research

Aware of these difficulties, the research doctor Coen Gho , of Dutch nationality, undertook very advanced studies, both in vitro and in vivo on the basis of his intuition. These studies were then published in the prestigious English-language Journal of dermatological treatment.

He knew there were different groups of stem cells in the follicular units. He had the idea of checking by experiments carried out in vivo and in vitro whether the follicular units survived their partial elimination and whether these partial extractions could regenerate new follicular units. Approximately 100/150 transplants from the occipital donor area were transplanted in five patients.

Exclusive HST grafting technique with very high success rate

The evolution of these grafts has been observed for a long time. After three months, between 92.1% and 104.1% (with an average of 97.7%) of the partial samples in the donor area had survived and had regenerated hair of the same quality as the original ones. After one year, between 91.1% and 101.7% (95.9% average) of partial implants of follicular units generated hair with the same characteristics as those collected in the donor area.

Then it was shown that taking portions of follicular units instead of the whole ones was exactly equivalent, with the considerable benefit of having a regenerated donor area. Thus, in this way, it has been possible to demonstrate that from a follicular unit, two identical units can be created, completely preserving the donor area. Subsequently, on the basis of this experience, the complete procedure currently being carried out was defined.

Dr. Gho patented a formula for a pharmacological compound containing exosomes and portions of the extracellular matrix that gives strength to tiny samples that are virtually free of tissue. The samples are kept in this bath for at least two hours. With this experience, corroborated by studies conducted by leading scientists such as Professor Kim, Professor Choi, Professor Reynolds, and others, it was understood that the proximal and distal parts of a follicular unit contain hair stem cells that cause hair growth.

Exclusive HST transplantation technique: regenerated donor area and multiplication of follicular units

In the case of partial longitudinal collection of follicular units, where the hair stem cells remain both in the extracted part and in the part left to the donor, it is possible to affirm that a donor zone is able to propose several harvesting per transplant.

It is a concept that constitutes today the most notable advance in the field of hair transplantation. Many patients with donor areas already poor in nature or damaged by excessive sampling due to other techniques, see it again possible to find a hair as dreamed.

Exclusive HST grafting technique: no scars, no dressing, light post-operative phase

In addition, with significant secondary benefits: such as not having to get a bandage after the procedure, given the minute incisions. Or the fact of not having a complicated post-operative path, but extremely simple and gentle.

Without scars, or hardening of the scalp, the minute implants of half a millimeter allow an extremely dense and close reconstruction in the receiving area, and in such a way provide an extremely natural result and a high density.
