Biotin has, perhaps, the most impact on stimulating hair growth. There’s no evidence showing that taking an excessive biotin supplement actually helps your hair, however. The effects seem to end when you reach the necessary daily requirement for biotin.


Biotin is found in so many foods, there’s almost no chance that you aren’t getting enough of it. The only reason some people have biotin deficiency is when their body can’t naturally process the biotin through the digestive process.


For people with biotin deficiency, an overdose of biotin is sometimes needed, in which they will take more than ten times the daily dose in the hopes that their body will process at least 10% of it. A more efficient alternative is injective the biotin directly into the bloodstream so that the processing stage is missed completely.


If your hair seems to be growing very slowly, get yourself tested for biotin deficiency. If you have it, try the supplements available in your country and watch your hair start to grow faster as you get the correct amount of biotin every day!

Vitamin B12

Vitamin B12 is responsible for red blood cell production. Your red blood cells carry oxygen and necessary nutrients through your body. Without enough red blood cells in your system, more than just your hair growth will begin to slow down!


The deficiency of red blood cells will cause your hair follicles to lack the oxygen and nutrients they need to function efficiently. Naturally, your hair will grow much slower when this is the case. Gaining the correct level of B12 each day will also allow your body to have enough red blood cells. The result is that your hair follicles will have everything they need to grow hair as fast as they can!


B12 can be found in red meats and eggs. If you’re a vegan or vegetarian, you may need to look into a B12 supplement to keep up with your daily needs. Otherwise, you risk having a B12 deficiency which will, in turn, slow down hair growth.

Vitamin A

Vitamin A is necessary for all forms of cell growth, including hair strands. In fact, hair grows faster than any other cell in the body, hence why you need enough vitamin A if you want it to grow that fast.


On top of that, vitamin A aids the skin cells in secreting sebum. Sebum is a moist substance that keeps your skin from drying out. Sebum is also secreted on your scalp and keeps your hair moist and healthy.


You can find a strong source of vitamin A in the following foods:

  • Sweet Potatoes
  • Spinach
  • Pumpkins
  • Carrots
  • Fish
  • Milk
  • Eggs

Vitamin C and E

Both vitamins C and E are antioxidants which prevent oxidative stress. Oxidative stress can block your hair growth permanently by damaging your hair follicles. Preventing this from occurring will allow you to keep your hair on your head for as long as humanly possible.

Vitamin C also helps to produce collagen which is an important part of your hair. Not only that, but vitamin C also improves your ability to absorb iron, another important element for your hair.


You can find a strong source of vitamin C strawberries, peppers, and citrus fruits. As for vitamin E, you’ll find that in almonds, sunflower seeds, and avocados.

Vitamin D

While many people think that sun exposure causes hair loss, they are sadly mistaken. The sun is your only source of vitamin D. Without adequate vitamin D levels, your hair will grow very slowly and possibly even fall out.


It is true that too much exposure to the sun is bad for your hair, but only to the point where you are getting sunburnt. If your skin is not burning under the sun, then you’re fine.

Make sure you don’t overuse your sunscreen. You do want to get some sun exposure or else your body will get quite weak.
