9 Expert-Approved Ways to Get Thicker Hair

Thicker, shinier hair might seem out of reach if you're dealing with thinning or fine strands, but the good news is, there are many ways to improve your hair health and add volume. While it's true that you can't change the size of your hair follicles—meaning those born with fine hair will always have fine hair—you can take steps to enhance the overall look and feel of your mane. There are also innovative products that can help bulk up each strand. Keep reading for nine expert-backed tips and tricks that will get you closer to thicker, fuller-looking hair.

1. Address Stress and Hormone Imbalances

Hormonal fluctuations can have a major impact on hair health, especially for women going through menopause, those with thyroid imbalances, or new moms. Estrogen is key for hair growth, and when levels dip, hair can start to thin. But stress also plays a role—high stress levels overburden the adrenal glands, often exacerbating hormone-related hair loss. Consider adaptogenic herbs like Ashwagandha or amino acids that support keratin production to help maintain hair thickness and growth.

2. Increase Your Healthy Fat Intake

Your diet significantly influences the health of your hair. Healthy fats, particularly omega-3s, can promote new hair growth, reduce breakage, and keep your scalp healthy. Foods like avocados, salmon, and whole eggs are packed with essential nutrients that support thicker, stronger hair. Adding these to your diet can make a big difference in the overall look and feel of your hair.

3. Cut Down on Heat Styling

Excessive heat styling weakens hair, leading to breakage and thinning. To keep hair thicker, try to air dry your hair whenever possible. You’ll not only help it grow faster but also make it look healthier. If you must use heat tools, always apply a heat protectant beforehand and consider investing in quality leave-in treatments to protect your hair’s natural texture post-shower.

4. Use Sulfate-Free Shampoo

Sulfates can strip your hair of its natural oils, making it more prone to thinning. Opt for sulfate-free shampoos loaded with nourishing ingredients that leave your hair healthier and shinier. You might miss the suds at first, but over time, your hair will thank you as it grows thicker and stronger.

5. Brush From Ends to Roots

Brushing your hair incorrectly can cause breakage, which leads to thinner hair. Start brushing from the ends and work your way up to the roots to gently detangle your strands without causing damage. Being careful with your hair’s ends, which are the most fragile, will help reduce breakage and keep your hair looking thicker.

6. Try Volumizing Products

The right styling products can create the illusion of thicker hair. Look for lightweight volumizing mousses to add lift and texture at the roots. Dry shampoos can also add volume and texture to finer hair types. These products make styling easier while giving your hair a fuller, more voluminous appearance.

7. Fill In Thin Spots With Root Cover-Ups

If your scalp is starting to peek through at your hairline due to thinning, root cover-up products are an easy and effective solution. These products instantly give the appearance of a fuller head of hair, making sparse areas less noticeable.

8. Give Yourself a Scalp Massage

A regular scalp massage can stimulate hair growth by improving circulation to the hair follicles. Studies show that consistent scalp massages over time can help thicken hair. Use a scalp brush in the shower to massage your scalp while shampooing to boost blood flow and encourage healthy hair growth.

9. Wash With Lukewarm Water

Just like heat styling tools can damage your hair, washing it in super hot water can strip your scalp of natural oils, leading to breakage. To keep your hair thicker, wash it with lukewarm water instead. Not only will this protect your strands, but it can also help reduce frizz.
