What Causes Hair Loss and Hair Thinning

Let’s start at the beginning by discussing why someone might be experiencing hair loss, thinning hair, or slow hair growth in the first place, beginning with gender. “There has been a historic assumption that hair loss is a male concern, and this is reflected in the traditional solutions available,” says Vegamour’s Dan Hodgdon, which bolsters no surprise that consumers are looking for products that tailor their approach to address female hair loss specifically. “Hair loss in women is incredibly common—over 80% of women will experience hair loss at some point in their lives, and over 40% of alopecia sufferers are women,” he adds.

“So many different factors can contribute to hair loss,” says trichologist Helen Reavey, who lists age, stress levels, diet, illness, hormonal imbalances, or even product buildup as potential causes. She continues that distinguishing the cause of hair loss is key, as treatment methods could vary widely. Hodgdon builds that certain conditions like alopecia or telogen effluvium (temporary hair loss after an episode of severe stress) can also have an impact.

“There are so many causes of hair thinning, and many with targeted treatments, that it is firstly essential to undergo a physical examination and discuss your history with a professional,” says dermatologist Dr. Blair Murphy-Rose, as your diagnosis will determine the most effective treatment. In addition to hair growth products, “there are other important ways to improve hair health; these include maintaining a well-balanced diet for adequate nutrition, getting sufficient sleep and reducing stress.” So, for best results, you’ll likely want to explore lifestyle changes whilst exploring hair growth treatments.

What Are Hair-Growth Products?

Hodgdon describes this category as “[products] that help promote and support a healthy hair-growth cycle”—essentially stimulating the hair follicle. Our experts explain most products look to address a single cause or symptom, which Hodgdon places into one of two categories: topical and ingestible treatments—the latter, Reavey says, has seen immense growth to support hair health from within. This could include items like best shampoo for hair thinning or collagen supplements.

The Key Ingredients You Should Look for in Hair-Growth Products

Whether you’re looking to prevent or treat hair loss, your first step may be consulting with a trusted dermatologist or trichologist to determine the root cause and create a plan of next steps. Saedi recommends prostaglandin analogs to help promote growth or supplementing your diet with biotin.
