Perhaps your dramatic hair cut was shorter than you thought. Perhaps you want to give your naturally thin hair a volume boost. Smart lifestyle habits can help your hair stay in good shape and prevent breakage.

Vitamins for hair growth can “help provide the hair follicles the necessary building blocks for healthy activities,” Joshua Zeichner MD, director of cosmetic dermatology at Mount Sinai Hospital, New York City. This means that hair follicles will function at their best.

Experts say that  vitamins for hair can make a significant difference. Lamees Hamdan MD, founder and CEO, Shiffa, says that hair contains the fastest-dividing cells in our bodies, but they are not essential for living. She says that the result is that hair cells are often the last to receive nutrition.

Another benefit? Hair vitamins can make hair stronger and healthier, as well as last longer. “There will increase hair production, yes. But more importantly, there’ll be an improvement in hair quality,” Julie Russak MD, a dermatologist who founded Russak Dermatology Clinic in New York City. You can have lots of hair but it won’t do any good if it’s weak and fragile.

Also, hair growth vitamins are not recommended for use in this context.They are not a substitute for a healthy diet.This will ensure your hair looks its best.

What vitamins are good to hair?

Experts believe that many over-the-counter vitamins that promote hair growth and thickness contain B complex vitamins, iron and protein.

You should always be aware of the recommended daily allowance (RDA) for each ingredient. This is particularly important for vitamins with iron or vitamin A as they can cause side effects. The handy guide of the National Institutes of Health can be used to help you make informed decisions about dietary supplements.

How long does hair growth vitamins take to start working?
Although hair vitamins may promise long-lasting results, you should not expect miracles.

“It takes time to grow hair,” Lilly-Rose Paraskevas MD, CEO, and director of Rose Dermatology, New York City.

Dr. Hamdan says consistent use of a hair-growth vitamin will help you grow your hair.If you don’t have any medical or hormonal issues, you will notice a decrease in hair loss within two months. She says that by month six, you should feel your hair thickening.

Dermatologists share their top picks for hair vitamins that will give you thicker, longer hair.

1. Nutrafol

These supplements were cited by nearly all of the dermatologists we surveyed as a top choice for hair growth. Debra Jaliman MD of New York City raves about these hair growth pills’ ingredient list. It includes a host of vitamins and antioxidants as well as keratin and resveratrol as well as biologically active compounds derived primarily from food and plants. She says that the product is a “very good product” because of its unique combination of all these ingredients. It has ingredients that are not found in other hair growth products.

2. Viviscal

This brand has been clinically proven to nourish hair, resulting in thicker and more long hair. Dr. Zeichner loves it. Viviscal is a unique marine complex that includes zinc, vitamin C and horsetail extract. Dr. Hamdan also votes for this ingredient, as it “is very silica rich.”

3. Collagen

You may have heard of people who consume collagen to improve their skin. But the ingredient could also be beneficial for your hair, according to Dr. Jaliman. She says some believe that collagen can be transferred to hair and scalp health. “The more collagen we consume, the younger our skin will appear and the healthier our hair will become,” she says.

There are many collagen products available, but Vital Proteins Collagen Peptides is our favorite. A scoop of this unflavored version will disappear into your morning smoothie.

4. OUAI Hair Supplement to Thinning Hair

Dr. Hamdan says that these supplements contain all the essential vitamins and minerals you require. They contain all of the essential vitamins and minerals as well as amino acid and silica. It’s also good! These hair growth pills are easy to use and can be taken daily.

5. NeoCell Keratin Volumizer for Hair

Dr. Russak says NeoCell is a product she likes personally. This formulation is designed to increase keratin for stronger and healthier hair strands, says Dr. Russak. It’s also affordable and gluten-free.

6. Dandruff

It’s not a shampoo to supplement your hair, but a good dandruff Shampoo is vital when you want to grow your hair. Dr. Russak says that it is not sufficient to supplement the body if the scalp or hair follicles are inflamed. I recommend that you use a shampoo that exfoliates and cleans the scalp regularly with mild fruit acids or salicylic acid. L’Oreal Professional Serie Expert Volumetry Shampoo is our pick. It will hydrate, add volume, shine and reduce oil buildup due to the salicylic acid.

7. Prenatal Vitamins

You may know prenatal vitamins provide the building blocks to optimal growth and function for mom and baby. But you might not be aware that they could also be beneficial for your hair. Dr. Zeichner says that most prenatal vitamins contain iron, B complex vitamins and minerals that will support hair follicles. Prenatal vitamins are recommended for hair growth. He particularly recommends those that contain Biotin, which is a B-complex vitamin that’s great both for hair and nails. Pink Stork Total Prenatal vitamins are rich in vitamin A, vitamin B, vitamin C and vitamin D to meet Dr. Zeichner’s requirements.
