WAY TO GO! That is wonderful. It is very freeing, isn't it!! Don't worry about the "nicking"... the more you shave, the easier that it will get. Are you using a regular razor? I use the HeadBlade. I found out about it from the founder of "Bald Girls Do Lunch". I feel like it makes shaving your head easier. You are brave! Hugs!
You're such a brave person!
Your challendge was to overcome yourself, and you did it!
Alopecia is much more hurtful for women, because of social stereotypes.
