Lifestyle is referred to the characteristics of inhabitants of a region in special time and place. It depends on day to day behaviours and functions of individuals in job, activities, fun and diet. In recent decades, lifestyle plays an important role on health. According to WHO, an individual health is related to lifestyle. Millions of people follow an unhealthy lifestyle. Unhealthy Lifestyle can cause problems like metabolic diseases, joint and skeletal problems, cardio-vascular diseases, hypertension, overweight, violence and so on. Now a days, every adolescent is facing many challenges which is related to stress that threatens the physical and mental health.The challenge is the overuse and misuse of the technology. Adolescence is the peak age of onset for serious mental illness which can lead to depression and psychosis. Adolescents with overload of stress from physical, emotional, social and sexual change can result in anxiety, withdrawal, aggression, poor coping skills and actual physical illness. The common behaviours of adolescents are watching TV, playing video games, hitting others, smoking and drinking alcohol, as lack of sleep, swearing, throwing things, and vandalism. Especially , during the time of support and guidance, adolescents often turns away from parents and health care providers.Alopecia means hair loss. The common types of alopecia are • Androgenic alopecia and • Areata alopecia Androgenic alopecia is also called as androgenetic alopecia. It causes baldness affecting both males and females. In men, there is loss of hair in a pattern beginning above both temples and then later the hairline will recede forming a characteristic “M” shape. Later hair will thin at the crown and later on will progress to partial or to complete baldness. In men it’s commonly seen as early as in teenage and increasing with age. After the age of 50 years, more than 50% of men are commonly affected by androgenic alopecia. It is a encountered problem with aging especially in elderly men. Commonly, balding is associated with aging, giving people a old look leading to feeling of distress and weary. It has an impact on their way of life which may even depress them to a great extent. Alopecia areata (AA) is a cause of noncicatricial alopecia. It occurs as a patchy, confluent or diffuse pattern. It may occur as a single, self-limiting episode or may recur at varying intervals over many years. Strong direct and indirect evidence supports an autoimmune etiology for alopecia areata. The origin of disease process is not fully understood; however, there are indications for a T-cell-mediated autoimmune process directed against an unknown autoantigen of the hair follicle. T lymphocytes that have been shown to be oligoclonal and autoreactive are predominantly present in the peribulbous inflammatory infiltrate. Alopecia areata are also associated with autoimmune disorders such as Addison’s disease, pernicious anemia, lupus erythematosus, diabetes mellitus, Down’s syndrome and others.Evaluation of alopecia can be categorised as invasive, semi invasive and non invasive. Individuals complaining of increased hair shedding, clinicians should investigate for potential triggers from the 3 months before the development of hair loss, including drug intake, systemic illness, or weight loss. Gynecologic history is very important in women, and hormonal evaluation is indicated in women with androgenetic alopecia and a history of irregular menses. Further, a family history of hair loss is characteristic in androgenetic alopecia and alopecia areata. Laboratory tests should evaluate iron and vitamin D levels and thyroid function.The wash test is a valuable tool in which the patient collects hairs shed during standardized shampooing. Trichoscopy, or dermoscopy and videodermoscopy of the scalp, may reveal features of a specific type of hair loss. Dermoscopy of primary and secondary cicatricial alopecia reveals decreased hair density and loss of follicular openings A scalp biopsy can be used for a more definitive diagnosis.Medical treatments approved by the US Food and Drug Administration (FDA) for androgenetic alopecia include topical minoxidil 2% for women and topical minoxidil 5% and the oral type II 5-?-reductase inhibitor finasteride (1 mg/day) for men. Hair transplantation, which is a surgical method of hair restoration, is an option for male and female patients over the age of 25 years with substantial hair loss.Available treatments for alopecia areata are they may induce hair regrowth but have never been proven to change the course of the disease. These include pulsed high doses of oral or intravenous steroids, topical high potency steroids under occlusion, photochemotherapy, and topical immunotherapy. MATERIALS AND METHOD :- The survey was done through an online way. With 100 responses among the adolescents. They were required to fill the questionnaire which included 15 questions related to the effects of lifestyle changes and alopecia. Then finally, the respective responses were verified and the analysis was prepared from the results obtained by making suitable pie charts for better understanding and information.RESULTS AND DISCUSSION:-The statistically analysed data are represented below:- These pie charts represents how much the participants are conscious about their lifestyle and hair loss which causes depression, anxiety, stress, health problems etc. From these pie charts it is proved that still the people are not conscious about their lifestyle changes.According to my survey, out of 100 participants 21% of people have an habit of eating outside out daily , 53% of people have an habit of eating outside out weekly and 25% of people have an habit of eating outside out rarely. 68% of people take vegetables and 32% of people don’t take vegetables regularly. 37% of people take fruits daily, 35% of people take fruits weekly and 28% of people take fruits once in a week. 27% of people’s BMI is slim, 49% of people’s BMI is fit and 24% of people’s BMI is obese. 27% of people consume non veg daily, 48% of people consume non veg weekly and 25% of people consume non veg once in a week. 55% of people have an habit of eating junk food while watching tv and 45% of people do not have an habit of eating junk food while watching tv. 33% of people have an habit of going out to restaurant with friends often and 67% of people goes once in a while. 48% of people sleep for 8 hrs in a day, 31% sleep for 6 hrs in a day and 21% of people sleep for less than 6hrs. 65% of people use mobile at late night and 35% of people do not have an habit of using mobile at late night. 53 % of people due to lack of sleep feel stressed and 47% of people do not feel stressed. 57% of people are suffering from hair loss in moderate condition , 20% of people in severe condition and 23% of are not suffering from hair loss. 25% of people think due to lack of sleep is the reason for their hair loss and 74% of people think it is not due to the lack of sleep. 13% of people have undergone treatment for hair loss and 87% of people haven’t undergone any treatment. 30% of people are aware of high lipid diet and may be junk food can be the reason for the hair loss and 70% of people are not are of high lipid diet. 43% of people have planned to change their lifestyle and 57% of people have not planned to change their lifestyle . Conclusion :-Adolescents need to be treated as a distinct segment of our population and it is important to realize and address their health and lifestyle problems. Inadequate sleep, depression and smoking were the leading unhealthy behaviours among the respondents. Families can play an important role to help these adolescents live a healthier life. Further research studies should be carried out to highlight issues of concern and their possible solutions in this population.?
