I have been dealing with the issue of hair loss since I moved to the UAE. I recommend to get natural oils and massage your scalp with them one or twice a week. Before you take a shower apply to your hair and scalp gently massaging the oil, keep it on for 15 mins or as long as you like and then shower. The oils I like olive, coconut, aloe vera; any oil really. I have tried many different kinds and they all do the job.
Try to get a shower head filter I have seen them at Carrefour. Trim the ends of your hair at least once every 4 to 6 weeks. Vitamins and supplements also might help, I recommend vitamin E 1000 mg. There is a supplement I took and I saw improvement: vegetal silica I took it because my eyelashes were falling out. It actually helped my lashes and hair. Diet is a mean issue too the healthier you eat the better and working out increase blood flow to the scalp as well, which promotes healthy and strong hair.
As for dry dehydrated hair I recommend a hair mask called macadamia oil deep repair mask. I picked mine up at Nazih and they have locations all over the UAE. It maybe a little pricey but it makes my hair so soft and smells amazing. My husband uses too and he loves it! It's worth a try.
I hope this helps! Good Luck!
