The Best Hair Thickening Products for Instant Volume

No matter your hair type, everyone can struggle with thinning hair. As someone with afro-textured hair, the first time I straightened it, I expected it to look as thick and full as it did in its natural curls. Reader, it did not. Since then, I’ve learned all the tricks of the trade to get naturally fuller, thicker hair. From extensions to hair thickening serums to rice water treatments and more, I’ve tried it all. But to truly understand the science behind hair volume and density, I sought expert guidance to help me find the best hair thickening products.

I spoke with Devin Graciano, hair stylist and Head of Product Development at Goldie Locks. Graciano enlightened me about the difference between hair density and hair thickness. Density is the number of strands on your head, while thickness is the width of each strand. Collectively, both create the appearance of your hair volume. So, to achieve thicker hair, it’s key to understand your hair type, as well as what’s causing your hair’s thinness.

How to Actually Get Thicker Hair, According to an Expert

Hair thickness is largely determined by genetics—but that doesn’t mean you can’t give your strands a boost. For naturally thinner hair, nourishing it inside and out is essential to keeping it healthy and full. If your hair is losing density, it could be due to aging (slower growth is normal over time), stress, childbirth, nutritional deficiencies, or genetic conditions like alopecia. Sometimes, a clogged scalp can also be the culprit—in which case, adding a scalp scrub to your routine can help stimulate circulation and encourage growth.

With all these contributing factors to hair loss or thinning, many of us will likely ask ourselves: can you fake it until you make it? When it comes to creating texture and volume, you’re in luck. Read on for Graciano’s insights on the best hair thickening products to give your tresses a more voluminous look.

As we get older, slower hair growth is normal and might result in thinning. Some people also experience hair loss from stress, childbirth, or nutritional deficiencies, as well as genetic conditions like alopecia.

Is there anything proven to thicken hair? 

Countless studies have explored ways to achieve thicker hair—from boosting density to temporarily plumping each strand. While DIY methods abound, there are also proven ingredients worth seeking out when thicker, fuller hair is the goal.

Ingredients That Can Help Thicken Hair

Ingredients that show a great improvement in hair thickness include:

• Saw palmetto
• Rosemary
• Scutellaria baicalensis
• Soy
• Wheat

Boosting hair density involves looking at both internal and external factors. Hair is made of sulfur, iron, oxygen, hydrogen, and nitrogen, so getting enough of these key minerals is essential for new growth. Deficiencies, along with factors like inflammation, poor diet, sleep, and hydration, can all show up in the health of your hair.

Do thickening products damage hair? 

Generally speaking, no. Hair thickeners typically consist of either hair fibers that attach to the hair or water-soluble polymers that can’t overtake your hair’s overall integrity. 

How long does it take for a hair thickener to work? 

For styling products, results can be seen in minutes. These formulas coat the hair shaft, creating the appearance of thicker strands almost instantly. Ingredients like hydroxyethylcellulose can plump each hair fiber within a few minutes.

When using supplements or treatments that target new growth, allow for a full hair growth cycle (around three months) before expecting visible results.

Daily Routines That Can Help Prevent Thinning

Consistency is key when it comes to thicker hair. In addition to using hair thickening products, try:

• Taking a balanced hair supplement to support growth from within.
• Eating a nutrient-rich diet and staying hydrated.
• Managing stress, which can have a direct impact on hair shedding.
• Doing a daily scalp massage. Just four minutes can boost circulation and stimulate follicles.

Bottom line: While genetics play a big role, the right combination of nutrition, lifestyle habits, and hair thickening products can help you achieve fuller, healthier-looking hair.
