Stress levels are high amid the pandemic, and an unfortunate side effect of stress is hair loss. But you don't have to let extra shedding get the best of you. Amazon shoppers found this biotin shampoo and conditioner that they say "really works to make your hair grow thicker." And the duo is currently on sale for just $23. To get a better sense of the benefits of biotin, we consulted Dr. Debra Jaliman, a board-certified dermatologist in New York City, "Biotin helps nourish the hair follicles and stimulate the growth of existing hair.," Dr. Jaliman tells InStyle. She adds that the vitamin helps with the production of keratin, which "is the protein that strengthens hair." You can get biotin in your system through an oral supplement, or you can apply it directly to your scalp with hair care products. The New York Biology shampoo and conditioner have biotin as their main ingredient, followed by argan oil, shea butter, ginseng extract, coconut oil, and amino acids. These elements work together to strengthen thinning or damaged hair and deep-clean your locks. The shampoo and conditioner can also help soothe an irritated or itchy scalp.
