Thinning hair and hair loss are things we’ll all face at one point or another, whether due to stress, hormonal changes, or simply aging. While it’s nothing to be ashamed of, it’s perfectly natural to want to add a little oomph to your locks — and the easiest way to do that is by incorporating the best shampoo for thinning hair into your beauty routine. Before we talk about a treatment, though, let’s break down some of the possible reasons for your thinning hair.
What causes thinning hair in women?
Wearing certain hairstyles, excessive chemical processes, hereditary factors, and nutritional deficiencies can all contribute to thinning hair. The most common cause, though, is hereditary female pattern baldness that tends to occur gradually over time. As we get older, so do our hair follicles, which shrink with age. This causes our rate of hair growth to slow down, and, in some cases, cease completely.
Also factoring into our thinning hair is a lowered production rate of estrogen — aka the female sex hormone — that occurs with age. In addition to regulating our reproductive systems, estrogen plays a big role in hair loss, as it encourages speedy growth and keeps strands on our heads for longer. When we’re producing less estrogen, there’s less new hair available to replace the strands that shed naturally, ultimately resulting in thinning.
What is the best shampoo for thinning hair?
The best shampoos for thinning hair are ones that address hair loss on multiple levels. Look for a formula that’s lightweight and rich in nutrients to aid in proper hair production and health, while also providing a volumizing effect.
You’ll also want to take your individual hair type into account. Hair that’s chemically damaged, for instance, may require a different formula than hair that’s sparse due to natural causes. Luckily for you, we’ve done the hard part of scouring beauty shelves across the interwebs for the best pick for every hair type.
