I would suggest that you check with your state for thier early developmental screening program. Most states will send someone to your home (free of charge) to check out your child's development and give you advice if this is something you need to look into further.
Since pulling hair is painful and she does it to the extent that she has pulled hair out, you should try to get to the bottom of why she does something that will be a red flag in a developmental screen (self injurous behavior, or SIB.)
This could be related to stress or a sensory need that she cannot process yet, which should be checked out with a developmental screen sooner, rather than later. I would try all kinds of other sensory-tactile replacements for the behavior (the bubbles and the jello sound fun!)
Good luck!
