Growing up, my family typically used whatever generic store brand shampoo and conditioner we happened to grab. I later developed sensitivities to perfumes which sadly prevented me from using products like Pantene Pro V, Suave and Garnier Fructise. I loved the smell of Burt's Bees products, but they dried out my scalp and left me feeling itchy and my hair feeling rough. Additionally, after coming down with Lyme disease and requiring powerful doses of antibiotics to treat that and other related illnesses, my hair started falling out. On top of that, I now have thyroid trouble which also contributes to my thinning hair. Hair loss isn't a widespread complaint among 24-year-olds, so I didn't know that there was anything I could do about it until my stylist mentioned Nioxin three years ago. I bought a small portion of the cleanser and conditioner on a holiday discount and have been hooked ever since! My hair still falls out at the same rate, I would say, but I'm positive it's due to my underlying health issues that Nioxin simply isn't designed to treat. However, the Nioxin definitely makes my remaining hair look great. My hair is very fine, and heavy conditioners can make it look greasy and dirty mere hours after a shower. That's not a problem with Nioxin. Aside from the previous issues, I also have dry and very sensitive skin and certain shampoo perfumes give me asthma attacks. The Nioxin conditioner keeps my scalp moisturized without causing an itchy reaction. Rather than causing an asthma attack, the fresh peppermint scent of this shampoo is almost like aroma therapy and feels like it opens my airways! It's a wonderful way to wake up in the morning and feel invigorated. The only reason I wouldn't suggest you purchase some of this great hair care line is if you're not a fan of peppermint! Otherwise, I can't think of anything negative about it!
