My Dear Welcome to Healthcaremagic! I have noted your description and assessed it in the light of your symptoms.As the name implies, ectodemal dysplasia is disorder in which ectodermal structures are poorly developed. Skin and its appendages are likely to malformed in these disorders which actually area group of diverse conditions with several common manifestations. Though there is little that can be done as per academic texts for hair growth, but I will tell you certain measures from experience with my patients that has improved their hair appearance and boosted their confidence. 1 Have a good healthy diet 2 Do not use too much and harsh chemicals on your scalp 3 Use hair voluminisers that will give them a dense look 4 Some people have reported good outcome by the use of Biotin which isa vitamin and is fairly safe even for long term use 5 another good step would be to wear a cap or some other type of protective covering which will prevent the hairs from being exposed to harsh weather conditions. 6 You may also go for vasodilators that will improve the nourishment to hair roots so that they last longer and new hairs growth is stimulated. You are likely to experience good results as you continue with these measures over months and years. Please be patient and watch the results. Best wishes from Healthcaremagic!
