All specialists agree: healthy hair starts from within. If your diet lacks certain nutrients, including vitamins, minerals, and proteins, your hair’s condition and thickness might deteriorate. Also, everyday stress, hormonal changes, collagen decrease, menopause, post-pregnancy, medication & over-styling can negatively impact your hair, often leading to breakage and excess shedding. While we don’t have full control over some of these factors, we definitely can manage our diet in such a way as to provide the hair with all the nutrients required for healthy growth.

Just like the rest of your body, your hair needs targeted nourishment to reach its bouncy potential. Sometimes it might be challenging to get the necessary nutrition only from your diet. In the speed century, it may be almost impossible to have the time to cook nutrient-rich meals every day. Don’t you agree? But thanks, God, we have supplements! One pill can make up for all the missing vitamins and proteins your body needs to grow strong and thicker hair. 

How supplements help hair growth? 

Studies suggest that hair loss is often caused by a lack of necessary nutrients, such as iron, zinc, niacin, vitamins A, D, E, fatty acids, selenium, folic acid, biotin, proteins, collagen, and antioxidants. According to research, nutritional deficiency may impact both hair structure and hair growth, leading to conditions such as telogen effluvium, androgenetic alopecia, female pattern hair loss, or alopecia areata. Proper nutrition is also linked with long, dense, thicker, shiny, and voluminous hair. All these lead to the same conclusion: taking supplements can reduce hair loss and make hair grow faster by eliminating nutritional deficiencies. 


No matter your hair type, you’ll likely notice results after boosting the level of proteins, vitamins, and collagen inside your body. Experts recommend taking supplements twice a year, during spring and fall, when the hair is shedding the most because of the seasonal change.

What is good for hair growth and thickness

Welp, let’s see what supplements are actually essential for hair growth and thickness: they should include one or more of the following minerals, proteins, and vitamins, of which deficiencies are known to cause hair loss:

  1. Iron – Iron deficiency is the world’s most common nutritional deficiency and is a well-known cause of hair loss. Iron is an essential mineral that your body stores in the form of ferritin. You can also say ferritin is a protein that stores iron for the body to use as needed. Ferritin can be found in many body parts, including hair follicles. When your body lacks iron, it can borrow ferritin from your hair follicles, weakening them. Studies confirmed an association between decreased ferritin levels and hair loss. Also, without iron, the body cannot produce enough red blood cells responsible for the transport of oxygen around the body. 
  2. Zinc – A deficiency of this mineral is known to cause hair loss and damage the existed hair, causing it to break. A study found that out of 312 people suffering from alopecia areata and androgenic alopecia, they all presented lower zinc concentrations in the body. They also found zinc supplementation to restore hair condition in most cases. 
  3. Niacin – Niacin, or vitamin B3, is needed for our bodies to convert carbohydrates into energy. It improves blood circulation and brings oxygen and nutrients to the hair follicle. Due to the effects of niacin on hair follicles, it’s believed that a deficiency of this vitamin may weaken hair follicles and cause them to produce thin hair. 
  4. Fatty acids – Essential fatty acids linoleic acid (an omega-6 fatty acid) and alpha-linolenic acid (an omega-3 fatty acid) may reduce hair loss by inhibition of 5α-reductase that converts testosterone to DHT — a hormone known to cause hair follicles to miniaturize, contributing to pattern hair loss.
  5. Vitamins D, A, E, and biotin (vitamin H) may also play a role in healthy hair growth.
  6. Antioxidants – Antioxidants are compounds that can neutralize oxidative stress damage. Many elements count as antioxidants, including zinc, selenium, and vitamins A, C, and E.

Worth mentioning that supplements are believed to work only when your condition is caused by nutritional deficiencies. There is currently a lack of data regarding the effects of supplementation in people without nutrient deficiency. So before taking supplements, it’s best to advise your doctor to confirm the causes of your hair loss and what your body actually needs.
