Follicular Unit Extraction (FUE). In this method, instead of taking out a whole sample strip, small, individual follicle grafts are cut using a machine and then transplanted. The process is more tedious and more time-consuming, but has been known to have a higher recovery rate and there are no risks of scarring because no cuts and stitches are required.
Losing your hair can be distressing, but if it is caused by thyroid disease it is most likely reversible. In the meantime, try to stave off further hair loss by treating your hair gently. Avoid brushing it excessively, using harsh coloring products, and hairstyles that pull on the hair (such as a tight bun). If you feel self-conscious about having thin hair or bald patches, consider wearing a scarf or wig while your hair grows back.
As I mentioned before, the causes of hair fall are innumerable, and so it becomes crucial to get to the root of the problem. The best way to go about dealing with the problem would be to get the correct diagnosis to begin with. This can be made simpler by finding the areas where thinning is most prominent and also monitoring how much hair you are losing whenever you comb or shampoo. Consult a physician to find out whether you have any underlying medical issues causing the hair fall.
The cause of female-pattern hair loss is unknown, but doctors said there is a strong genetic component. The risk can come from male or female relatives. Though it looks as if the hair is falling out, that's not really what's happening. Cotsarelis said hair follicles are becoming smaller and producing hairs that may be so small that you can't see them.  Women tend to retain more normal, thick hairs than balding men do.
For those concerned that the existing treatments lack a certain sci-fi quality, behold the Laser Comb. The Laser Comb recently became only the third hair loss treatment to receive FDA approval. And it is the first that doesn’t use drugs or surgery. By stimulating follicles with a low-level laser, the hand-held device was shown in test trials to increase hair volume in a majority of patients.

Traumas such as childbirth, major surgery, poisoning, and severe stress may cause a hair loss condition known as telogen effluvium,[19] in which a large number of hairs enter the resting phase at the same time, causing shedding and subsequent thinning. The condition also presents as a side effect of chemotherapy – while targeting dividing cancer cells, this treatment also affects hair’s growth phase with the result that almost 90% of hairs fall out soon after chemotherapy starts.[20]


Male pattern baldness involves a receding hairline and thinning around the crown with eventual bald spots. Ultimately, you may have only a horseshoe ring of hair around the sides. In addition to genes, male pattern baldness seems to require the presence of the male hormone testosterone. Men who do not produce testosterone (because of genetic abnormalities or castration) do not develop this pattern baldness. 

Harsh hairstyles or treatments: Hairstyles that consistently use rubber bands, rollers or barrettes, or pull hair into tight styles such as cornrows, can inflame and scar hair follicles. So can incorrectly used chemical products such as dyes, bleaches, straighteners or permanent wave solutions. Depending on the degree of damage, resulting hair loss can be permanent.
Traction alopecia - certain hairstyles such as when you pull on your hair tightly can cause scarring of the hair follicles. If pulling is stopped before scarring to the scalp then your hair will grow back normally. Nervous habits such as continual hair pulling or scalp rubbing can also cause scarring and ultimately permanent hair loss. Excessive shampooing and blow-drying can also cause hair loss.
Disruptions in the normal length of each phase, which can cause hair loss and hair thinning, may be the result of a number of internal and external stimuli. These are also what we call the triggers and causes of your hair loss. As a quick example, dieting can leave the body stressed and in need of important nutrients. Because of this stress, hair growth may be cut shorter than usual and there is an early onset of telogen or shedding of hair.
Tinea is the medical word for fungal infection, and capitis means head. Tinea capitis is fungal infection of the scalp that for the most part affects school-age children. Tinea capitis is more common in black African or African-American scalps. This condition is rare in healthy adults. Bald spots usually show broken-off hairs accompanied by a dermatitis. Oral antifungals can penetrate the hair roots and cure the infection, after which hair grows back. Sharing hats or combs and brushes may transmit tinea capitis.
