Wow! Thank you ladies for all your helpful reviews for this great product. I used it yesterday for the first time and am delighted with the results. Background: My hair has been looking yucky lately for some inexplicable reason. I have really fine/thin, straight, naturally dark blonde hair with a few highlights. I try to be really careful with it -- I condition regularly, I don't color or highlight too often, I don't use a flat iron or curling iron, I get regular haircuts, but still my hair has lost its lustre and has the texture has changed. It looks o.k. the day I wash & style it, but the next morning it looks truly terrible -- the ends are oddly fluffy, like a dry cotton ball that's been pulled apart. When I brush it, it doesn't look much better. I guess it's age-related (sigh). I tried some deep conditioners and they provided a temporary quick fix, but I knew I needed to do something else to help restore my hair. Enter MUA and Emergencee. It has smoothed the ends (didn't wash my hair today and it looks fine) and has given me some hope! My hair hasn't looked this good in awhile and I will be using this product faithfully every 2 weeks from now on.
