Hair cloning is one of the most anticipated areas of research in hair restoration medicine. The possibility of creating new hair follicles in a laboratory leads many to believe it could become the definitive solution to alopecia. However, although scientific advances continue, as of 2026 it remains an experimental technique and is not approved for patients in Spain or any other country.
Below, we explain what it is, how it would work if it became a reality, the current state of research, and what treatments currently exist to combat baldness.
REVIEWED BY MEDICAL COMMITTEE
Hair cloning is a regenerative medicine approach that aims to create new hair follicles by culturing and multiplying the cells responsible for hair growth in the laboratory, and then implanting them in hairless areas.
The main difference compared to hair grafting is that it doesn't use existing follicles, but rather seeks to generate new ones. While a hair transplant redistributes existing follicular units from the donor zone Towards areas with lower density, hair cloning seeks to overcome the limitations of the donor area, so unsuitable cases could resort to hair transplantation.
In theory, it would be enough to obtain a small sample of follicular cells, multiply them under controlled conditions, and generate a greater number of follicles capable of producing hair. However, although it is one of the most promising lines of research within hair medicine, as of 2026 there is still no approved protocol for its application in patients.
The interest in this experimental technique lies in its potential to transform how alopecia is treated. If it were possible to obtain thousands of new follicles from a small hair sample, one of the main limitations of hair transplantation—the availability of follicular units in the donor area—would cease to exist.
This possibility would be especially interesting for certain patient profiles, such as:
In any case, it is essential to remember that these applications belong to the field of research and that, for the moment, they cannot be offered as a real alternative to hair transplantation.
Although there is still no approved technique that allows for the safe generation of new hair follicles, its operation would be based on three phases:
The first step would be to obtain a small sample of healthy follicles through a biopsy or a micro-punch taken from the donor area. The goal would be to isolate the cells responsible for hair growth for later analysis in the laboratory.
Once obtained, the follicular cells would be transferred to a specialized laboratory to multiply them under controlled conditions.
After multiplying, the cells would be implanted by microinjections into the areas affected by alopecia so that they organize themselves, form new functional follicles and produce hair naturally.
On paper, hair cloning may seem like a relatively simple procedure: extract some cells, multiply them in the laboratory, and implant them again. However, putting it into practice poses one of the greatest challenges in regenerative medicine and healthcare regulations.
The main scientific obstacles that researchers face are:
Furthermore, these types of cell therapies are currently strictly experimental and cannot be applied to patients due to biological regulations.
Research has advanced significantly over the past few decades, although it is still far from becoming a treatment available for humans.
One of the best-known projects was the one developed by the Aderans Research Institute, which focused on multiplying dermal papilla cells to stimulate hair growth. Although the program helped expand knowledge about hair follicle biology, it failed to develop a therapy that could be translated into clinical practice.
Meanwhile, various research teams in Japan have achieved promising results in animal models, where structures similar to hair follicles have been generated that are capable of producing hair.
These advances demonstrate that follicular regeneration is scientifically possible, but translating those results to humans remains a much more complex challenge, and to this day, there is no approved treatment in any country.
There is no confirmed date at the moment.
The most optimistic forecasts suggest that the first larger clinical trials could take place between the end of this decade and the next. However, for more than a decade it has been common to find news reports stating that this technique will be available "in about ten years," but the reality is that each advance presents new challenges that must be resolved before a safe treatment can be offered.
Before it can become a routine treatment, it will be necessary to demonstrate not only that it works, but also that it offers stable long-term results and meets all the safety guarantees required for its use in patients.
Meanwhile, there are currently hair treatments backed by scientific evidence that offer proven results for those seeking a solution for hair loss.
Although hair cloning represents one of the most promising research approaches for treating alopecia, the reality is that it will be years before it can become part of routine clinical practice. In the meantime, there are safe and proven effective treatments that can slow hair loss, improve hair quality, and even restore hair density.
The available options are divided into two main groups.
Hair treatmentsTreatments such as hair mesotherapy, platelet-rich plasma (PRP), and hair biostimulation can slow hair loss, increase density, and combat its progression. It's important to remember that these treatments don't create new hair follicles, but rather improve the health of existing ones.
In any case, the most appropriate treatment will always depend on the type of alopecia, the degree of hair loss and the individual characteristics of each patient, so it is essential to carry out a prior medical diagnosis.
Although both hair cloning and hair transplantation aim to combat alopecia, their foundations and level of development are very different:
| Features | Cloning | Hair graft |
|---|---|---|
|
It generates new follicles |
Yes, that is its theoretical objective. |
No, it uses existing hair. |
|
Donor area dependency |
It seeks to reduce or eliminate this limitation. |
Yes |
|
Clinical approval |
No |
Yes |
|
Current availability |
No |
Yes |
|
Predictable results |
Not yet |
Yes. Studied and predictable results |
|
Hair permanence |
Pending clinical demonstration |
It's final |
Currently, hair transplantation remains the only available surgical technique capable of restoring lost hair density with predictable results supported by scientific evidence.
However, the success of the treatment depends not only on the technique used. An accurate diagnosis, proper assessment of the donor area, and a medical team experienced in hair transplantation are also essential.
For this reason, before deciding where to have a hair transplant, it is advisable to prioritize aspects such as safety, the experience of the medical team, post-operative follow-up and personalization of the treatment, over unrealistic promises or decisions based exclusively on price.
Hospital Capilar It has clinics in Madrid, Murcia, Pontevedra, Vigo and Seville, where each patient receives an individual assessment to determine the most appropriate treatment according to their case.
No. Although both procedures aim to combat alopecia, they work in completely different ways.
Hair transplantation redistributes existing follicular units from the patient's donor area to areas with lower density. In contrast, hair cloning aims to create new follicles by multiplying follicular cells in a laboratory.
Currently, only hair transplantation is an approved and available technique for patients.
No. As of 2026, there are no approved hair cloning treatments for patients. Although research has made progress in the laboratory, a safe, effective technique available for clinical use in humans has not yet been developed.
This cannot be confirmed at this time. To answer this question, clinical trials will need to be completed demonstrating that the new follicles maintain stable growth for years, retain a normal hair cycle, and produce hair with characteristics similar to the original follicle.
Until such scientific evidence exists, it cannot be guaranteed that hair generated through cloning will have a permanent effect.
It depends on the type of alopecia and the individual characteristics of each patient. While some people may benefit from medical treatments or injections, others will achieve better results with a hair transplant. Therefore, the first step should always be a personalized hair loss assessment.
If approved, it will not replace hair transplantation but will be a complement for certain patients.
To this day, hair transplantation remains the only surgical technique capable of restoring hair with predictable results supported by scientific evidence.
No. As of 2026, hair cloning is not available in Spain or any other country as an approved treatment for patients. Although various research teams continue to work on developing this technology, it is still in the experimental phase and is not part of clinical practice.
