Treating Alopecia requires an accurate diagnosis of the type of Alopecia. Externally, apply coconut oil weekly. This will promote hair growth and restore the scalp to its optimum condition. Gotu Kola will be an excellent stimulant for hair growth. It is unlikely that the Alopecia in children is linked to any vitamin deficiency. Feel free to come to our Natural Medicine Dispensary where any specific nutritional need can be discussed. I am not sure what has been used already.
I would suggest that you consider homeopathy as the treatment is based on a Constitutional Approach treating the disease at the root level, hence enhancing the resistance power of the child. However, the remedy is individual based and requires a consultation. Please feel free to visit me at the Natural medicine Dispensary at our Cavendish Branch. Regards Reena
