Do Vitamins Help Hair Growth?
Yes, vitamins do help hair growth.
But, scientists say that taking oral supplements to improve your locks can only increase the growth of your hair if you're seriously deficient in key nutrients. Otherwise, these hair growth supplements may not be so effective because your body won’t absorb more of a particular nutrient than needed. 
If you think you're deficient, you may want to supplement with a high-quality vegan multivitamin.
What Deficiencies Cause Hair Loss?
Deficiencies that cause hair loss may include:
- Vitamins - C, D, E, B-Complex (specifically Riboflavin/B2, Niacin/B3, Biotin/B7, Folate/B9) 
- Minerals - Iron, Zinc, Selenium
- Fatty Acids
- Protein, and other essential nutrients 
Besides, hormonal changes, stress, age, poor nutrition, over-styling, and numerous other factors can cause hair breakage and excess shedding.
How Long Do Hair Vitamins Take to Work?
Hair vitamins may take from a few weeks to several months to work if you take them consistently and have no hormonal or other medical issues causing hair loss. So, it’s unrealistic to expect to see the results overnight.
“Biotin is a water-soluble vitamin that supports the growth of hair, skin, and nails by helping to break down fats and carbohydrates.” Dr. Dendy Engelman, Dermatologic Surgeon
What Is the Best Vitamin For Hair Growth?
Budget-Friendly, easy to use, packed with effective yet safe doses of hair growth vitamins and other essential nutrients, and targets multiple root causes of thinning hair and loss.
For me, these are the qualities needed by the best hair supplements.
