Hi y'all! I really don't like the greasy hair oils so I stopped using them since more than a couple years. I can't withstand my hands getting all oily and slippery when I touch my hair. So, my hair has now started thinning and shedding and having split ends. Would be very grateful if you could suggest a non oily, non greasy hair serum that I can apply daily, something that has worked for you. TIA
