Thank you @mefely. That's an interesting statement, does not help regrow, but does help keep it. I did not know this, and will look into that. If you have looked online, I'm sure you have seen that hair loss can be due to many things, from digestion, to hormonal changes, to stress, and vitamin and mineral defiencies, and dryness. I am wondering what additional stressor is created affecting hair when taking Hydroxyurea. I took a pause at this last statement and did a quick check. and this is what I found: Hydroxyurea is indeed very drying, as it can cause very dry skin, hence the itching people have talked about in this blood cancers and disorders thread, as well as constipation, among other side affects. A dry gut can cause hair loss. Perhaps massaging the scalp with almond oil, enhanced with a few drops of rosemary, chamomile and clary sage essential oil might help too? Almond oil is very hydrating an soothing for the rest of the body too. Let me know your thoughts please.
