I had alopicia when molly was 15 months old I started noticing when i lost more hair in the shower I only had 2 bold patches the size of 10ps and with a courses of steroid cream it all started to grow back after 3 months ish. i'd go to the docs it can affect you emotionally aswel i lost a lot of confidece with it and still after 5 years i'm constantly checking . They did put it down tp stress as it wasn't directly after i'd had her.
Hope all goes well for you , there is also a herbal tablet from holland and barrot you can buy called Silica complex it strengthens the hair and nail its really good, i took these aswel as the steroids in fact i only stopped taking them when i was pregnant with alfie.
