Androgenetic alopecia (AGA) was previously known as seborrheic alopecia, or early baldness. This type of hair loss is a degenerative change in the hair follicles of the scalp caused by the action of androgens on the hair follicles of the scalp. What is the difference between male and female androgenetic alopecia? Androgenetic alopecia differs between men and women. In clinical diagnosis, men are called male pattern alopecia. Women are more aptly called female-pattern alopecia, and patients are more receptive to it. However, both are a condition of hair thinning and loss that occurs as we age. The only difference is the shape and location of hair loss in men and women. Men show receding forehead hairline or thinning hair on the top of the head; in women show gradual thinning of hair in the central part of the scalp or diffuse hair thinning, the front hairline is generally not affected. Second, how to choose the timing of treatment for hair loss? Because AGA is a degenerative disease, the earlier the treatment, the better the effect. Treating the intervention as soon as the hair loss starts will preserve the hair that has not had time to fall out and save a lot of effort in treatment. Third, how to choose the oral medication to use for hair loss? Finasteride oral, suitable for male pattern baldness use, may have an effect on male sexual function, but this side effect may have a relationship with psychological factors; female pattern baldness oral medication can use spironolactone, but the first three months need to regularly check the blood potassium concentration, the dose does not exceed 100mg/d. Male pattern baldness oral finasteride and rubbing minoxidil have no end of treatment, male oral medication finasteride Finasteride, after achieving better results, can be used in reduced doses, and can be used again at any time if hair loss occurs again after discontinuing use. According to the patient’s physical condition can be accompanied by complementary drug therapy, such as oral vitamin B complex, compound glycyrrhizin tablets, zinc glycyrrhizin, cimetidine tablets, excessive anxiety and insomnia patients, can be taken orally before bedtime Doxepin and so on. Fourth, how to use topical drugs better? Topical application of drugs, the effect of topical minoxidil for both men and women can be. Female patients are recommended to start using from low concentration. Minoxidil liquid can be used in accordance with the instructions to achieve the therapeutic effect, if the local use of micro-needles, nano-microcrystals or plum needle percussion, regular introduction of growth factors, plant hair growth solution, with the use of synergistic minoxidil solution to promote drug absorption, can have better results. V. Is platelet-rich plasma (PRP), fractional laser treatment or buried thread treatment effective for AGA? Platelet-rich plasma is injected superficially into the hair loss area, and fractional laser treatment and scalp buried wire treatment are also clinically used. They are effective in treating and promoting hair loss regrowth to a certain extent. But there is a lack of effective scientific statistical data analysis. Sixth, what is the role of Botox injection for hair loss? Botox injection in small doses and micro-drops can reduce the secretion of sebaceous glands in the scalp for a period of time, which can play the role of hair loss prevention and hair loss regeneration to a certain extent. 7.Does low-power laser irradiation treatment for hair loss have any effect? Low-power laser irradiation treatment can improve the scalp environment to a certain extent, which is beneficial to hair loss regeneration. In clinical practice, we often choose to use weak laser 650nm hair growth cap or low power helium-neon laser irradiation. 2 times a week, usually a course of treatment for 3 months. VIII. Do I need to use medication again after hair transplantation? Will the transplanted hairs fall out again? Hair transplantation can be used on the scalp after follicular atresia. Will the hair after hair transplantation shed again? Theoretically, no, but there is no clear scientific research evidence to prove that it does not shed after a long time. Consider another way of thinking, even if the implanted hair does not fall off, other nearby hair shedding will form the phenomenon of a lone tree, seriously affecting the aesthetics. Do I need to abstain from eating to treat hair loss? A light diet, regular work and rest, and a calm mind can reduce androgen secretion to a certain extent, which is also beneficial for the prevention and treatment of hair loss. In particular, it is better not to eat milk and dairy products, sweets, fried food, junk food and so on. Ten, how long does it take to get results from hair loss treatment? Because the process of hair loss treatment is long, it takes a process to control shedding and then grow new hair after treatment, and most of them take 6 months to more than 1 year to see obvious results. Therefore, the treatment must be persistent and not be abandoned halfway. During the treatment process, multi-angle photos, video comparison, hair mirror, dermoscopy and other methods can be used to observe the hair follicles and hair growth changes before and after the hair loss treatment to give the patient more confidence in the treatment.
