What can stimulate natural hair growth?

As dermatologists and hair experts explain, there are factors we can control that can help reduce hair loss and breakage.

"Maintaining a balanced diet that includes a full range of macronutrients and micronutrients is the best and most sustainable way to support healthy hair growth (as well as an overall healthy body)." But unless you know you have a vitamin deficiency, you won't be sure. Hair is hard to make an impact on.

"Instead, eat well, minimize the use of heat and dyes, and use hair masks and heat protectants. Don't expect miracles, but doing these things simply supports the condition of your existing hair fibers and optimizes the environment for healthy hair growth.

You can also break some bad habits. "Some studies have linked smoking to premature baldness and graying of hair." "For many people, stress may also trigger hair loss, either as alopecia or the onset of alopecia areata. Autoimmune alopecia."

“It may be impossible to eliminate stress, but try to find some coping strategies that will put you in the right mindset to handle and deal with stress more effectively when challenges arise.”

Do hair growth serums really work?

Many tests have proven that a good hair growth serum can work, but be realistic; you'll never wake up with miraculously thicker hair.

"Many hair serums contain conditioning agents such as peptides/amino acids and hyaluronic acid. These natural compounds may be used as a preventative measure."

If your hair is fine, the last thing you need is slowed growth or the use of products that are too heavy. This lightweight serum won't weigh down finer hair and left most testers with stronger, thicker hair.

It helps reduce hair loss in many people, while also moisturizing the scalp and dry ends. It clears up dandruff for everyone with essentially no irritation.

It didn't score as high as expected in tests, but overall it's described as a "mild" and "relaxing" serum that helps strengthen brittle strands.
