Unraveling Frizz: How To Solve For Your Type

Hair Serum for Frizz

We’ve all experienced the frustration of dealing with unruly, frizzy hair at some point. Whether it’s due to humidity, dryness, or damage, frizz can turn a good hair day into a battle against the elements. But that’s why we’re here, to offer you some understanding, and solutions to the dreaded frizz.

The Culprits: What Causes Hair to Frizz

  1. Humidity Induced Frizz Imagine a damp day, and your hair seems to have a mind of its own, puffing up in all directions. This phenomenon is the result of humidity-induced frizz. Hair acts like a sponge, absorbing moisture from the air, causing the strands to swell and become porous. Porous hair is particularly susceptible to frizz as the cuticle layer lifts, leading to a rough and unruly appearance.
  2. Dryness Induced Frizz On the opposite end of the spectrum is dryness-induced frizz. Hair that lacks sufficient moisture becomes dehydrated and loses its natural oils, making the cuticle layer rough and susceptible to frizz. The lack of moisture also causes individual strands to stand out, giving hair that unmistakably frizzy appearance.
  3. Damage Induced Frizz Chemical treatments, excessive heat styling, and environmental stressors can all damage the hair’s structure, making it prone to frizz. When the hair’s cuticle layer is compromised, it loses its ability to lay flat and smooth. Damaged hair lacks the structural integrity necessary to repel moisture and environmental factors, exacerbating frizz issues.

Solutions: How to Keep Frizz at Bay

  1. Humidity-Defying Strategies To combat humidity-induced frizz, the key is sealing the hair’s cuticle and minimizing moisture absorption. Using anti-humidity hair products, such as serums and sprays, can provide a protective barrier against excess moisture. Look for products that contain ingredients like silicones and natural oils, which help to repel water and keep the hair smooth.
  2. Hydration for Dry Hair For dryness-induced frizz, restoring moisture is paramount. Incorporate a hydrating shampoo and conditioner into your hair care routine. Deep conditioning treatments or hair masks enriched with ingredients like shea butter, argan oil, or glycerin can replenish lost moisture, making the hair more manageable and less prone to frizz.
  3. Repairing Damaged Hair Damaged-induced frizz calls for a comprehensive hair repair approach. Start by trimming off split ends to prevent further damage from traveling up the hair shaft. Use protein-rich hair treatments to rebuild the hair’s structure and strengthen its overall health. Additionally, opt for sulfate-free shampoos and mild, nourishing conditioners to minimize further damage.

Slugging: The Ultimate Hair Moisturizing Hack

In the ever-evolving world of TikTok trends, one particular phenomenon has taken hold of the haircare community: slugging. Don’t worry, no snails are (directly) involved. 

Derived from the popular skincare trend of slugging, which is a well-known moisturizing technique that involves slathering your face with an occlusive product as the last step in your evening skincare routine in the hopes of deep moisturization. Hair slugging offers a similar approach to combating dryness and restoring hydration by applying a moisturizing product from the mid-length to the ends of the hair and leaving it in overnight, resulting in impressive transformations by your morning cup of coffee! 

Just as slugging in skincare involves sealing in moisture with occlusive products, slugging hair aims to retain hydration by using moisturizing products overnight. The technique primarily targets dry and damaged hair, providing a much-needed boost of moisture and preventing breakage. While various products can be used for slugging hair, popular choices include leave-in conditioners, hair masks, and serums.


To jump on the slugging hair trend, choose a leave-in conditioner, hair mask, or serum suitable for your hair type. After washing and towel-drying your hair, apply a generous amount of the moisturizer from the mid-length to the ends, thoroughly coating the strands. For added effectiveness, you can gently detangle your hair with a wide-toothed comb before applying the product.


Once the moisturizer is applied, gather your hair and cover it with a silk scarf or similar covering. This step helps create a barrier that locks in the moisture, preventing it from evaporating overnight. Alternatively, a clean sock can be used as a makeshift hair wrap – seriously, put a sock on that bun and call it a night! 

By allowing the moisturizing product to work its magic overnight, slugging hair enables a prolonged and intensive treatment. This method deeply penetrates the hair shaft, replenishing lost moisture and nutrients. The result is softer, silkier hair that is less prone to breakage and split ends. 


So when in doubt, slug it out! 

How to Make Hair Thicker: 6 Hacks for Fuller Tresses

How to Make Hair Thicker: 6 Hacks for Fuller Tresses

Disclaimer: The information provided is not intended as medical advice. For any medical concerns, always contact your doctor.

Having hair that looks full and luscious is the ultimate hair goal, especially if your hair is anything but. Because when it comes to hairstyles, like most things in life, we tend to crave what we don’t have. So for those of us with ultra-fine hair, having thick, bouncy, voluminous manes is typically at the top of our wish lists.

Unfortunately, as anyone with baby-fine hair will tell you, achieving even the slightest bit of body and volume can feel like a near-impossible task. Trust us — we’ve been there. That’s why we tapped our team of in-house hair care experts to give us the scoop on quick and easy hacks for how to make hair thicker. And trust us when we say that these six tips can make all the difference for those of us with thin hair. Let’s get started!

1. Get frequent trims

Have you ever noticed that your hair strands always seem a bit thicker on the days immediately following a haircut? That’s because even the slightest trim can help even out your hair and remove unwanted split ends, making hair look fuller and healthier. 

We recommend getting a trim every six to eight weeks to ensure your ends stay well-maintained, giving you healthier hair.

2. Reconsider your cut

Speaking of frequent trims, if you’ve been struggling to make your long, thin hair appear fuller, a quick fix for how to make hair thicker may be reconsidering your length. While long hair certainly has its perks (dramatic hair flip, anyone?) longer hairstyles tend to weigh the tresses down, making your hair goals that much harder to achieve. Opting for a short, blunt cut can actually help add body, volume, and fullness to your natural hair.

The next time you go to your hairstylist, ask about ditching some of your length in favor of a super trendy bob or lob cut. Shorter styles add instant thickness and body to otherwise limp, thin hair while also ridding your mane of unwanted breakage and damage. Double win!

3. Cleanse and condition the right way

As if dealing with thin hair wasn’t challenging enough, it’s no secret that these hair types also tend to become greasier faster than others. That’s because the shaft of fine hair tends to be smoother and less porous, which allows natural oils to sit more visibly on top of the hair. To help combat this and promote the feeling of hair thickness, we recommend focusing your shampoo on the roots where these oils tend to collect and build up

For an extra boost toward fuller hair, opt for a volumizing shampoo. Function of Beauty offers a custom strengthening, lengthening, sulfate-free shampoo and conditioner that can also assist with oil control (and other beauty goals you might have).

Even with a well-balanced shampoo, the approach to how to make hair thicker, the answer isn’t necessarily shampooing more often. That can dry out your locks and cause damage instead of hair thickening. Stick to sudsing the roots of your hair and then, apply your conditioner strategically. Avoid conditioner on your scalp, as it can weigh down your hair and make thin hair appear even less full. Instead, use just enough to coat the strands from the mid-shafts to the tips to keep your hair looking fresh and voluminous up top.

Pro Tip: Find out how often you should wash your hair.

4. Choose better styling products

If you’ve ever experimented with a DIY coconut oil treatment or a rich, moisturizing mask, you may have noticed how heavy and flat your hair felt afterwards. That’s because ultra-thick hair oils and styling creams typically aren’t the best options for those with fine or thinning hair. Though they hydrate locks and may prevent hair breakage, some oil-based hair products can weigh your delicate hair down, causing it to look limp and greasy — definitely not like the fuller, healthier hair of your dreams.

You don’t have to give up on hair care products in order to achieve the look of thicker hair. Instead, we recommend sticking to those that offer “hold” and “texture,” like a non-aerosol dry shampoo, sea salt spray, texturizing mist, or volumizing mousse. Not only are they light enough for your thin strands, but they can also give the appearance of thicker, fuller hair by coating the hair shafts in polymers, which can create a hair thickening effect.

Of course, thin hair needs moisture and care, too! When you feel the need for an extra dose of hydration, shine, or thermal protection, we’ve got you covered. 

Our leave-in treatment, though rich and nourishing like a styling cream, is also fully customizable according to your natural hair type. This means that those dealing with fine tresses, hair thinning, or even hair loss can reap its restorative benefits without the risk of any buildup or residue.

5. Play with your part 

Okay — hear us out. We know it sounds simple, but switching up the way you part your tresses is actually one of the easiest ways to promote the look of fuller hair. Tend to opt for a straightforward middle part? Try a hairstyle with a deep side part for an instant dose of body and volume. 

If you’re already parting to the side, flip your perspective and part on the other side. The change can have a lifting effect on the strands that are normally pressed down, creating the look of fuller hair in only a few minutes. Then, just sit back and collect the many compliments you’ll receive using this healthy hair trick.

6. Rethink the heat

We all know that heat styling isn’t the best thing for our hair health. But let’s be honest — sometimes, we just need a blow dryer to give us that sleek, polished, thick hair look that’ll get us through the week. That said, if you’re pondering how to make hair thicker, you may want to reconsider your hot tool usage — especially if a flat iron is involved. While they’re great for shiny, smooth hairstyles, they can also cause your hair to appear flatter and thinner, which is the opposite direction of your quest for fuller hair.

You don’t have to ditch your flat iron, though. Try using it to create sleek, beachy-style waves, which will not only give your strands some extra width but will also add dimension and texture so that hair appears fuller. Even better, allow your hair to air dry naturally to enhance your hair’s natural texture before finishing it off with a few spritzes of texturizing sea salt spray. Remember to protect your hair health when using hot tools: to avoid split ends, try using a heat protectant spray or hair serum that fights off heat damage.

Easy Solutions for How to Make Hair Thicker

While we’d like to think of ourselves as hair miracle workers, we’re not physicians and we can’t give advice on medical conditions like hair thinning, alopecia, or baldness. We’d definitely recommend a doctor or dermatologist for that. But we can help you on your mission to find out how to make hair appear thicker, fuller, and more voluminous. 

Getting more frequent trims, changing up your haircut, using a thickening shampoo, choosing pro-volume hair styling products, switching your part, and trying out new styles with hot tools are easy hacks for how to make hair thicker — or at least look like it is.
