According to Krysta Biancone, “Yogurt is a great way to moisturize your hair; it can help give it a smooth and glossy finish. You can apply yogurt to your hair as a mask or use it as a conditioner. It contains lactic acid, which is a natural cleanser that can help remove the buildup of dirt and oil from your scalp. It also contains proteins that can help strengthen your hair and make it more manageable. Additionally, the probiotics present in yogurt can help promote healthy hair growth.”
