Abstract:
Alopecia areata is a prevalent autoimmune skin disease resulting in the loss of hair on the scalp and elsewhere on the body. It usually starts with one or more small, round, smooth patches on the scalp and can progress to total scalp hair loss (alopecia totalis) or complete body hair loss (alopecia universalis). The scalp is the most commonly affected area, but the beard or any hair-bearing site can be affected alone or together with the scalp. Alopecia areata occurs in males and females of all ages, but onset often occurs in childhood. Over people 147 million worldwide have, had or will develop alopecia areata at some point in their lives. According to Ayurveda, pitta dosha is the primary cause of hair loss. Pitta dosha could be reversed through diet and lifestyle modifications. Ayurvedic medicine for hair loss contains herbs that can arrest hair fall and improve hair growth.Keywords:

Alopecia refers to hair loss. It can D A™ÂˆA™Â´ ect the scalp or other parts of the body, and can be localized or widespread. It may be due to hair shedding, poor quality hair, or hair thinning and can be scarring or non-scarring in nature. Hair grows on most parts of the skin surface, except palms, soles, lips and eyelids. Hair thickness and length varies according to site. Vellus hair is fine light in color, and short in length. Terminal or androgenic hair is thicker, darker and longer. A hair shDA‘– grows within a follicle at a rate of about 1 cm per month. It is due to cell division at the base of the follicle (hair bulb). AÂe cells produce the three layers of the hair shDA‘– (medulla, cortex, cuticle), which are essentially made of the protein keratin. Hair growth follows a cycle. However, these phases are not synchronized and any hair may be at a particular phase at random. AÂe hair cycle can be divided into 3 main phases: A¢Â€Â¢ Anagen: AÂis is actively growing hair. A¢Â€Â¢ Catagen: Transition phase of 2-3 weeks when growth stops and the follicle shrinks. A¢Â€Â¢ Telogen: Resting phase for 1-4 months, up to 10% of hairs in a normal scalp. Over shedding is known as telogen effluvium It occurs 2-6 months DA‘–er an inciting event that stops active hair growth. Telogen effluvium is commonly caused by following reasons: A¢Â€Â¢ Fever, weight loss, pregnancy A¢Â€Â¢ Surgical operation, illness or psychological stress A¢Â€Â¢ Medications (contraceptives, anticoagulants, anticonvulsants) A¢Â€Â¢ Others (unknown) Shedding can persist for years (chronic telogen effluvium.
Pattern hair loss is due to hormonal influence and increases with age. Male pattern alopecia D A™ÂˆA™Â´ ects vertex and temporal scalp. Female pattern alopecia
Defects the anterior scalp. Hair shDA‘– defects can be congenital, or acquired due to disease or injury. Hair shDA‘– abnormalities can be diagnosed by dermatoscopy or more intensive examination of the hair.
Light therapy is safe and used to treat androgenetic alopecia. It is postulated to enhance blood flow in the scalp. It has also been suggested to improve the wound healing process in post hair transplant patients and hasten hair growth. However, the evidence is weak. A multicenter trial reported that male patients with androgenic alopecia exhibited a statistically significDnt increase in average hair density.
Similar results were shown in a study comprising women with androgenic alopecia [9]. In a second study of 103 males and 122 females with pattern alopecia that completed the study, HairMax LaserComb (with 12, 9 and 7 beams) was reported to result in increase in terminal hair density versus trial subjects in the control group [10]. Ongoing trials are investigating the efficDcy of other light therapy devices in various types of alopecia [11]. Lifestyle changes Good scalp care to keep hair clean with stimulating massage, and the safe use of a hair dryer. Maintaining exercise and stress control, eating healthily food rich in protein, vitamins and minerals, like iron. One should avoid birth control pills, anabolic steroids, alcohol and smoking. Finally cDmouflDge with wigs and hair pieces. Surgical and injectable Surgical treatment for hair loss will not be discussed in this paper. AÂis can be referred from Sattur SS. Several injectable can be used including: Platelet Rich Plasma (PRP)

Finally, we should look into PRP. AÂe use of platelet growth factors to stimulate hair growth and reduce hair loss has achieved quite e A™ÂˆA™Â´ ective results for both androgenic alopecia and alopecia areata, noted in small scale studies. We await large scale randomized controlled studies on the use of this modality. AÂis area is indeed promising, but it is clear that with the lack of intellectual property potential, pharmaceutical companies would hesitate to fund a large clinical trial. Botulinum toxin AÂe science behind this is the relaxation of scalp musculature, hence decompressing blood vessels in the scalp and increasing oxygen delivery. DHT is converted to estradiol in oxygen rich medium. About a 60 week study has reported increase in hair growth and reduction in hair loss in males with androgenic alopecia.
AÂis can be Metformin or rosiglitazone can be prescribed to women with polycystic ovarian syndrome. Hormonal treatment with antiandrogen medicines may be used for women with hirsutism. E A™ÂˆA™Â´ ects may take 6-12 months, and the medicine needs to be continued for years. Spironolactone can reduce excessive hair growth. A synergistic effect is achieved when combined with the contraceptive pill. Combined birth control pills that contain estrogen and progesterone: cyproterone are e A™ÂˆA™Â´ ective Side e A™ÂˆA™Â´ ects include mood swings, loss of libido and weight gain. Conclusion In the realm of hair loss, low level light therapy is a fascinating area deserving of further research. With the interest in non-invasive treatments growing, personally I believe combination therapy with minoxidil, anti-androgens and low level light therapy would be the gold standard treatment for hair loss in the future. As for hirsutism, it is not yet possible to prevent a genetically predetermined cause. Insulin resistance associated with obesity can be reduced by diet and lifestyle changes. Prognosis is dependent on the cause. AÂe most common types of excessive hair growth is permanent. Hirsutism has a tendency to worsen with age.

Feline alopecia is one of the most common reasons why cats are presented to their primary care clinician. Hair loss can be self-inflicted or spontaneous. Self-inflicted hair loss is usually caused by a pruritic skin condition such as allergy or ectoparasite infestation. Spontaneous hair loss may be caused by damage to the hair by factors such as infection, ectoparasites, immune-mediated disease or neoplasia. It may also be caused by hair cycle arrest due to endocrine disease or metabolic stress, which can lead to either anagen or telogen defluxion. Investigation should start by identifying the cause of hair loss through trichography plus specific tests for the type of hair loss. Investigation of pruritus should include elimination of ectoparasites, food trial and possible allergy testing. Specific tests for spontaneous hair loss include routine haematology and biochemistry as well as endocrine function tests, thoracic radiography, abdominal ultrasound and skin biopsy.

The relationships between hair loss, hair growth, and vascular supply in the human scalp have not been precisely delineated. Alopecias from severe inflammatory processes which destroy the follicular unit have been fully documented. The combination of genetic susceptibility and androgenic inhibition of follicular growth in male and female patterned baldness is well recognized, but the role played by the vascular system is unknown. Little is understood concerning the pathogenesis of the mildly inflammatory alopecias, exemplified by alopecia areata, alopecia totalis, and pseudopelade of Brocq. Chronic diffuse thinning of the hair in women in the absence of known hereditary factors, while apparently becoming increasingly common, has not been satisfactorily explained. In a recent study, Kligman1has shown that temporary thinning of scalp hair following severe fevers, infections, pregnancy, and heparin administration is due to accelerated production of normal telogen hairs. The causative mechanisms in this group likewise remain obscure. This

The genetic background and some environmental factors have been reported as cause of hair growth disturbances. The damage of the biological rhythm of hair growth causes the decrease of length of phase and stunted hair growth, leading to diffuse alopecia. The scheme of hair loss treatment, by means of preparations affecting pathogenetical mechanisms of diffuse hair loss development is offered. The clinical evaluation of hair post treatment condition is given as well. The clinical study has shown high therapeutic efficacy of proposed scheme for treatment of patients, suffer from "acute, chronic diffuse hair loss", androgenetical alopecia. Authors conclude that proposed scheme allows obtaining marked results.

Female pattern hair loss, or female pattern androgenetic alopecia, is a nonscarring alopecia with a multi-factorial etiology that mostly affects postmenopausal women and is characterized by a reduction in hair density over the crown and frontal scalp. The clinical picture is characterized by a diffuse rarefaction of scalp hair over the mid-frontal scalp and a more-or-less intact frontal hairline without any signs of inflammation or scarring. Although the disease poses only a cosmetic concern, it is chronic and may have a significant negative psychological impact on the affected person. The aim of treating female pattern hair loss is to reduce hair loss and, to a certain extent, succeed in promoting hair regrowth. Various treatment methods are available, but it remains unclear which are the most effective. Early initiation of treatment and the combination of various modalities seem to be more efficacious than monotherapy.
