roll your eyes and start pissing yourself laughing
educate yourself on what healthy hair actually is, then ask her to define it and explain how chemicals will make the hair healthier (a relaxer is hugely damaging)
show her the before and after threads on NC/ link her to the Curly Girl book and Scott Musgrave Facebook pages (both have loads of before and afters)
find new friends
tell her that two thirds of the world's population has naturally wavy or curly hair, so maybe our hair should be the benchmark of what is healthy and normal
ask her not to comment on your hair unless she has something nice to say, you like her very much so it's very hurtful. Rinse and repeat.
