Hi! I recently lost 120 lbs over 2.years, slowly and sensibly. Suddenly I'm losing half my hair! Biotin and collagen slowed the fall but it's just not coming back. It's been a year. I take 10,000 of biotin daily. It's just not working. I have tried everything from nutrients to supplements to topicals. Nothing. I've had all the blood work done, thyroid checks, you name it. Everything looks fine and ive paid some pretty high prices on things that just don't work. And yes i took them over long periods to give them a chance to work.
Someone finally suggested ( I watch my diet and "macros" and weightlift, that I might not be getting enough good fats in my diet. Made sense! I once lost a lot of weight due to another problem. When the problem resolved I lost my hair again but started eating my old way. The weight came back but so did my hair. Full curly and lustrous! Now ive lost the weight again (plain discipline this time) and bye bye hair! I've recently heard it's cause it's lack of good fats and oils. It's a catch 22 because nuts, seeds, avocado etc are great but quite high calorie. Anyone else battling this?
