The 27 best products under $30 for thinning hair, according to experts

It may seem inevitable that your hair will thin as you grow older (sigh), but there are actually several reasons your hair is thinning that have nothing to do with age. Experts agree that taking care of your hair from the inside out can make a big difference in both the appearance and rate of hair loss — and there are tons of Amazon products for thinning hair available online. Bonus: The ones on this list are all under $30.

Dr. Howard Sobel, founder of Sobel Skin and attending dermatologist and dermatologic surgeon at Lenox Hill Hospital in New York, New York, agrees that multiple factor can be at play when it comes to thinning hair. "Hair loss can be a result of many different factors ranging from your lifestyle to your genetics," he tells Mic. "Our stress levels and diets can impact our hair’s ability to grow or keep us from losing hair, but for women, hormones and hairstyling also play a role."

So how do you keep your locks lush and healthy going forward? On top of taking care of your scalp and using thickening shampoos and conditioners (which are often infused with biotin, keratin, and other nourishing vitamins), it's also really important to eat a nutrient-rich diet. But remember, it might take a little while to see a change. Dr. Sobel agrees: "Improvements are never going to happen overnight, be patient. You may not notice a change right away, but trust the process and notify your dermatologist of what’s happening."

If you aren't sure where to find the best products for thinning hair, here's a round-up of some extremely affordable and effective options that experts recommend.
