Which hair growth supplement works best?

B vitamins play a role in hair growth and are “essential for metabolism and nervous system function,” says Dr. The supplement industry is controversial, since it is not regulated by the Food and Drug Administration (FDA), but there are still many vitamin manufacturers that conduct clinical trials with their products and hire doctors and, in the case of vitamins for hair growth, board-certified dermatologists to oversee safety and effectiveness. For more information, we contacted Dr. Kim Nichols, board-certified dermatologist and Nutrafol expert (opens in a new tab), to understand what makes a hair growth vitamin safe and effective.

Keep reading to learn more about the do's and don'ts of hair supplements, and to find the best hair growth vitamin for you, no matter your flavor, hair goals, or dietary restrictions. Nichols also reminds us that we must trust science. “If you're looking for a new hair growth supplement, be sure to do your research,” she says. It's important to buy products that are backed by science, meaning that they have been proven to be clinically effective.

And while the FDA doesn't regulate the supplement industry, you can check if your supplements have been clinically tested by researching online or simply by checking the back of the bottle. And keratin, he tells us, is the structural and protective protein that forms much of our hair, skin and nails. Therefore, when you ingest nutrients that support keratin production, Dr. Nichols says you're reinforcing this natural protein in your body.

For example, Dr. Nichols says, “There have been studies that show that high levels of vitamin A may be related to the weakening of hair follicles.”. This is only the case when excessive supplementation occurs. When you ingest too much vitamin A, your hair follicles speed up and grow too big, your hair sheds quickly.

This is why it is important to take a supplement that has proven to be clinically effective, since the optimal dosages per ingredient have been taken into account. Some users also claim that vitamins for hair growth cause their skin to purge or break more than usual. Nichols says, “There's no solid evidence that hair growth supplements cause acne breakouts.”. However, some vitamins don't always work well with each other.

For example, excess B vitamins, such as biotin, can cause skin dehydration and eventually cause acne breakouts. That's why it's so important to read the ingredients and consult with a local board-certified dermatologist. I love this Kierr supplement, which incorporates coconut and elderberry oil into its formula, but focuses on getting your daily dose of biotin. The most popular B vitamin, biotin, is a key element in promoting healthy hair growth, explains Dr.

Biotin is accompanied by an increase in the production of keratin, which is the main component of hair makeup. Kim Nichols, MD, FAAD is a board-certified dermatologist who trained at Harvard University. He has worked with several celebrities and trains other dermatologists and plastic surgeons on how to administer injectables for natural-looking results. When it comes to hair growth, there are many vitamins that can help stimulate hair, according to Singh.

Meena Singh is a dermatologist and hair transplant specialist based in Kansas, known for her informative videos on hair growth. One user called them the best vitamin gummies and said, “They helped me grow my hair from the bottom of my ears to the tips of my shoulders in about 4 months. Vitamin D deficiency has been linked to hair loss and, in some cases, a health professional may recommend a supplement (2,. And if your regular diet just doesn't work, you might want to look into options such as collagen powder and vitamins for hair growth.

Complex, rechargeable hair growth supplements filled with biotin, zinc and iron don't disappoint when it comes to strengthening hair from the inside out. The vitamin can be expected to increase the speed of hair growth, but it won't increase thickness, he says. Prose's customizable Root Source supplement includes “millet”, a 100 percent natural whole grain filled with an active molecule called miliacin and omega-6 fats that “acts directly on the hair follicle to stimulate hair growth,” Mignon explains. We love this option because of its promise to strengthen hair from top to bottom, from the scalp to the ends, by incorporating vitamin A.

Similarly, research is inconclusive as to whether folate and vitamin B12 are effective for hair growth in people with an adequate intake (2,. You probably know that prenatal vitamins help provide the building blocks for optimal growth and function for both mother and baby, but you may not realize that they could also be beneficial to your hair. Here, dermatologists share the seven best hair vitamins on the market that will help you achieve longer, thicker locks. Several critics praise the fact that this supplement stopped her hair loss (in many cases due to extreme diets and poor nutrition) and allowed her hair to resume at an impressive rate.
