And thanks to the overwhelming number of hair loss products out there, that dream can become a reality. Shoppers especially love the Bosley MD Hair Growth Starter Kit, and it's currently half-off on Amazon ahead of Presidents Day weekend. The system comes with a nourishing shampoo, volumizing conditioner, and thickening treatment, all made with vegan, paraben- and sulfate-free formulas that are safe for color-treated hair. A couple of the main ingredients in these products include rosemary extract to reduce scalp inflammation and improve circulation and sunflower seed extract to soften your hair. They also have pumpkin seed extract and saw palmetto, which both block a molecule called DHT that's responsible for hair loss. Together, these products can thicken and rejuvenate dry, brittle hair. Courtesy Shop now: $21 (Originally $42); amazon.com To get the most out of the products, the brand recommends using them every day for at least 30 days. Start by massaging the shampoo into your scalp for around a minute before rinsing it out, then apply the conditioner from the middle to the ends of your hair and let it sit for up to five minutes before rinsing. Once you're out of the shower, rub the thickening foam treatment into your scalp and roots and leave it in.
