These hair vitamins have saved my hair. Between losing weight & stress, my hair was falling out. Although they were expensive, I bought these hair pills. It’s a one month supply for 88$. However, I only take 2 of the recommended 4 pills per day so it will last me 2 months. It took less than a month to see results. My hair loss was definitely a combination between nutritional deficiency, stress, & other things. This may not work for everyone, but if your situation is similar I 1000% recommend these. It can take up to 3 months to see results, but like I said, I saw results in less than a month. LTKbeauty
