body2hair, sorry to leave you hanging on this question. Since Dr. Cole had not heard of a linkage between N-WASP and hair growth prior to the article you cited, I tried contacting the lead researcher to see if I could find out more. Unfortunately, I haven't heard back from him yet.
Obviously very little is known about the protein N-WASP in regard to hair loss and hair growth; this study appears to be the first one to examine the link. Although the findings are compelling, Dr. Cole pointed out that any possible applications of this research to humans are likely still far away. It’s important to note that success in mice doesn’t indicate that it will work in humans. Scientists have been able to grow hair in mice in a variety of conditions (for example, it is possible to regenerate hair follicles in mice) but have yet to successfully duplicate most of these findings in humans. However, any potential solution or treatment for hair loss is exciting and we’ll be interested to follow any further studies of N-WASP use in humans.
Hope this helps a little!
