Iris,
i wonder if this is something that reacts differently to different hair types? and i also wonder what difference the accompanying conditioner makes(so far - we have all used different combos) - because ofcourse, they also have different ingredients, i bet they are reacting to this differently as well.
when i added the salt to the conditioner by 8yo dd walked in - her eyes got big and she said "oh no mommy - not salt, your hair will fall out!" and i admit, when i saw the name of the original thread - i chuckled and thought this was the craziest thing i had ever heard.
