Hair transplant in Spain is a safe and effective intervention, in which the follicles are extracted from the area that is not affected by baldness and are implanted in the area to be treated. This may raise the following question: if I have hair implanted without gray hair, can gray hair appear after the hair graft in the recipient area?

What are gray hair?

Gray hair is understood as hair that has lost its color naturally and acquires a whitish tone. Specifically, there is a progressive loss of melanin, a pigment that gives color to the hair, this being a common symptom of what is known as hair aging.

The hair transplant procedure is minimally invasive and simple. It basically consists of the extraction of the follicular units of the donor zone, the one that is not affected by alopecia, and are grafted in the area with baldness. Ultimately, it is the patient's own hair that is used to successfully perform the procedure. FUE hair implant.

This is important to keep in mind to resolve the doubt about whether gray hair can appear after a hair transplant. The answer is yes, Yes, gray hair can appear after a hair transplant in the same way that they would come out if we did not undergo said surgery. The appearance of gray hair is unrelated to the implantation of the follicles in a hair transplant, that is, the progressive loss of melanin will occur in the same way over time even if hair without gray hair is implanted since the hair follicles maintain their life cycle.

The opposite is also the case, since the rumor that the gray hairs do not fall. In case of having gray hair before the hair graft, the grafted hair will grow with that lack of pigment. In this sense, it is important to remember that patients with gray hair should dye before hair transplant, since otherwise it makes it difficult for the medical team to extract and implant the follicles when transparent gray hair is perceived at a microscopic level.


The passage of time is the main factor that causes this loss of hair pigment. It is something that we cannot avoid, in the same way that imperfections appear on the face with age, the hair also suffers from capillary aging.

Suffering episodes of stress has consequences for our hair health. In the same way as the stress causes hair loss, can also contribute to the development of premature graying.

disease development

Although more and more people are deciding on hair implants to put an end to baldness, the intervention is not feasible in all cases. Among the unfavorable situations for a hair transplant, is having gray hair one of them? Is it possible to perform a hair graft with gray hair?

The truth is that gray hair is not an impediment to proceed with the hair implant as long as it is dyed beforehand. Gray hair at the microscopic level is practically imperceptible, considerably hindering the process of extraction and implantation of the follicular units. This is why it is necessary to dye the hair before a hair transplant to successfully perform the surgery.

What is taken into account in a hair diagnosis?

To find out if a patient can undergo a hair implant, it is essential to make a medical diagnosis. It's about a capillary analysis by which the medical team determines if the patient is fit or not suitable for hair grafting, in which a number of factors are taken into account.

If the donor zone not enough to cover receiving area affected by baldness, the result is not as expected and hair surgery is not recommended. However, if the degree of alopecia is not very high, in most cases of patients with androgenic alopecia can be subjected to hair grafting.

Scalp condition

Another of the factors that are taken into account in a capillary diagnosis for the capillary implant is the state of the scalp. In case of suffering any scalp disease, it is important to stabilize it before the capillary graft, as occurs in cases of dermatitis o folliculitis.
