Hair transplant in men

HAIR TRANSPLANT IN MEN

Hair loss represents a distressing issue affecting an outsized portion of the population, including up to 85% of males, and its incidence increases with age. Though many causes of hair loss exist, far and away the foremost common etiology is androgenic alopecia (AGA), an androgen-sensitive pattern of hair loss that affects men. Non-surgical modalities exist which can halt the progression of androgenic alopecia and even help grow new hairs (i.e minoxidil, finasteride, dutasteride, low-level laser light therapy, platelet-rich plasma, adenosine,
ketoconazole).
It is essential to know the relevant anatomy and physiology of hair, and therefore the hair cycle, so as to maximize the outcomes of hair transplantation.
 Hair follicles have a hair shaft, two surrounding sheaths one is an inner sheath and another one is the outer sheath, it also contains a germinative bulb. The follicle divides into three sections: infundibulum (from the skin surface to the sebaceous follicle duct), the isthmus (from the sebaceous duct to the arrector pili muscle insertion), and the inferior segment (from the muscle insertion to the bottom of the matrix).
 The bulb is the deepest segment of the hair follicle it contains a hair matrix that creates the hair shaft, it also has dermal papilla which regulates growth.
 Terminal hair is thick pigmented hair at the upper side of the scalp, beard, axillary and pubic region, they are all androgen sensitive. The other hair on the body including parietal and occipital scalp, they are androgen independent.
 Vellus hair is short, fine and non pigmented which found on the adult that covers much of the body.
 Follicular unit is a naturally occurring group of hair that seen on the scalp which consisting of many terminal hairs mostly 1 to 4, it also has sebaceous gland, duct and an arrecotor pili muscle. The collagen band which surrounds the FU is named the perifolliculum.
 Androgenetic alopecia (AGA) is the common cause of hair loss which androgenetic affects testosterone and dihydrotestostertone and disrupt the growth cycle. AGA cause thinning and miniaturization of terminal hairs to vellus hairs.
 The Donor site is the non alopecic area where donor terminal hairs harvested for implanation. The safe donor site of the scalp lies between the mid-occipital. Basically, there are 65 to 85 FUs cm within the occipital donor scalp
 What is a Hair Transplant?
A hair transplant is a surgical procedure. First, the surgeon will harvest ‘donor’ follicles from one a part of your scalp, like the rear of your head, which is genetically immune to balding. Next, they're going to move them to the ‘recipient’ site, wherever you've got hair loss. You don’t got to attend a hospital for a hair transplant – it’s an outpatient procedure that uses an area anesthetic to numb the scalp. Depending on your needs, you'll require multiple sessions. Almost 1000 to 4000 hair follicles are transplanted per session and it takes several hours.

FUT Vs FUE Hair Transplant Surgery

There are two main sorts of hair transplants available: follicular unit transplantation (FUT) and follicular unit excision (FUE). While other techniques exist including somatic cell procedures they're less common and don’t have equivalent proven results. FUT is additionally called ‘strip surgery’ and involves harvesting a little patch of skin which the surgeon divides into smaller units. They then place the units into incisions at the recipient
site, before suturing the injuries closed. Meanwhile, FUE involves transplanting individual hair follicles by employing a tiny punch tool. While FUE is more intensive for the surgeon, it's less invasive and painful for the patient. 
Who Can Have a Hair Transplant?
Not every man is a perfect candidate for a hair transplant. If your hair loss is extensive and you've got only a few donor hairs available, your surgeon won't be ready to offer you the results you would like.
