Hair Regrowth – What You Need To Know?

Luscious hair is something many people strive for as it is seen as a symbol of health and beauty in many cultures.

Hair is an important part of your body, and just like any other component, it needs nutrients to thrive and grow properly.

Many nutritional deficiencies can be linked to hair loss. There are always factors other than your dietary intake that can affect hair loss and growth. These include hormonal function, genetics, and aging.

However, these factors can be overcome with proper nutrient intake and supplementation.

Now that you know what causes hair loss, take a look at what can be helpful for hair regrowth.

Hair Growth Ingredients – What To Look For in a Vitamin For Hair Growth?

There are several important vitamins and minerals to look for when shopping for the best supplements and vitamins for hair growth and thickness.

Among these are:

B Vitamins (such as biotin)
Vitamin C
Vitamin D
Vitamin E
Iron
Zinc

Something important to keep in mind is that supplementation with all these micronutrients is only effective when observed in individuals who already have been diagnosed with a nutrient deficiency, per research^[1] studies.

While biotin is a B vitamin and is likely the most common supplement ingredient discussed for hair growth, there is still little research on its benefit for those who are not deficient in it.

It is very rare for an individual to be deficient in biotin, as it can be found in various foods commonly found in the average person’s diet.

More research is needed concerning biotin supplementation and hair growth. However, you will likely find it in most hair growth products as it has been so polarized.

Vitamins For Hair Growth – What Vitamins Are Good For Hair Growth?

Vitamin C, an antioxidant, can play a very important role^[2] in hair growth as well. It can help protect hair from oxidative stress, which ultimately prevents your hair from aging too quickly.

It is also necessary for the formation of collagen, which is an important component of the structure of the hair. Due to this, supplementation with vitamin C, or getting enough of it in your daily dietary intake, could help prevent hair loss.

Biotin (also known as vitamin B7) is a water-soluble vitamin, often known for its hair growth benefits. It is a vitamin that functions in protein synthesis i.e., keratin production; a protein that helps form healthy skin, hair, and nails. (Source)^[3]

Biotin also involves creating red blood cells which carry oxygen and nutrients to the scalp and hair follicles.

Vitamins D and E, iron, and zinc are also important minerals and vitamins for hair growth. Vitamin D deficiency can be linked to hair loss, and research^[4] has shown that supplementation of vitamin D may be successful for hair growth treatment.
Vitamin E is also an antioxidant which can protect from oxidative stress and shows promising hair growth results, according to this study^[5].

Iron-deficiency anemia is one of the most common mineral deficiencies, with one of the most common symptoms being hair loss. If the deficiency has been determined by your physician, supplementation with iron, as well as ensuring to get enough in your daily dietary intake, can be beneficial for hair regrowth. Additionally, iron can be considered one of the best vitamins for hair loss.

Zinc deficiency can also be related to hair loss, with beneficial results seen from supplementation, as seen in this study^[6].

“Hair growth supplements are helpful for anyone who is experiencing hair loss, hair thinning, or for those who just want thicker or longer hair,” says Dendy Engelman, M.D., board-certified dermatologic surgeon at Medical Dermatology & Cosmetic Surgery in New York City.

Tips For Choosing the Best Supplements For Hair Growth

So how do you choose the best hair growth supplements for you?

First, identify what nutrient deficiencies, if any, you may have. We recommend consulting your primary care physician to help identify this, you can also consult a registered dietitian who offers these services.

Once this is determined, focus on those ingredients when searching for your supplement. If you are not deficient in any nutrients, you may not see the best results.

Research has shown^[7] that those who have nutrient deficiencies achieve better hair growth from supplementation than those who do not.

Always be sure to read the label carefully, we recommend choosing a cGMP registered facility, this is a third party tester that identifies the actual claimed amounts of each ingredient are truly in the supplement and tests them for purity. A cGMP label on the supplement package will identify this.

As always, show your physician the supplement you wish to take so they may approve it. This is especially important if you are pregnant, lactating, under 18, or already taking other medications.
