This personally has worked for me and is backed by trials. I love being a vegetarian, but did not like the effects it had on my hair, including thinning patches and loss of the front baby hairs. I gave this brand a chance 30 days ago, and it WORKS!!! Their Gro line is vegan and clean, using centuries old holistic products like tumeric and mung bean to promote hair and scalp health. No toxic hormones or chemicals either. I definitely see the baby hairs growing back and my hair line is denser/thicker. I bought this with my own money, it has helped me and I hope this helps others. I works really well when used with the biotin supplement gummies. My hair grew down to my back after stressful finals and board exams. My stamp of approval is given to this.
