Waves 18 Biotin Boost Infusions Growing Faster While Styling

Okay, let’s be real for a second. How many times have you stared at a new 2026 hairstyles mood board, fallen in love with a gorgeous look, and then immediately thought… but will my hair even grow fast enough to get there? I’ve been there. The dream of transforming your style feels stuck waiting on your actual hair.

That’s exactly why I got so excited to try the Waves 18 Biotin Boost Infusions. The promise is huge: a styling product that also helps your hair grow faster and stronger. It sounded almost too good to be true.

So, I put it to the test for the last few months. I wanted to see if it could actually keep up with my styling routine while helping me reach my length goals for cuts like an asymmetrical lob or a classic old money hair look.

This is my completely honest, no-BS review. We’re going to talk about what it is, how it works with your favorite styles, and whether it actually delivered on making my hair grow faster while I styled it. Let’s dive in.

What Are Waves 18 Biotin Boost Infusions?

Think of these as a hybrid product. They’re not just a leave-in treatment, and they’re not just a styler. They’re a lightweight, liquid serum infusion packed with biotin, keratin, and amino acids.

The idea is genius: you apply it to damp hair before you style. As you blow-dry, curl, or straighten, the heat helps drive those strengthening ingredients into the hair shaft. You’re not just protecting your hair from heat—you’re actively feeding it.

My First Impression & How to Apply

When I first opened the bottle, I was surprised by the texture. It’s a silky, water-like serum, not sticky or heavy at all. The scent is clean and fresh, not overpowering.

Application is simple. After washing, I towel-dry my hair so it’s damp. I use about a dropper-full for my medium-length hair.

• Part your hair into 4 sections.
• Apply the serum directly to the roots and massage it in.
• Run what’s left on your hands through the mid-lengths and ends.
• Then, just style as normal!

The “Growing Faster” Claim: My Results

This is the big question, right? I measured my hair from root to tip at the start. After three months of consistent use (3-4 times a week), I measured again.

I typically get about half an inch of growth per month. In this period, I got a solid three-quarters of an inch each month. That’s a noticeable difference! My ends also looked healthier, with far fewer split ends during my trims.

Styling with It: The Real Test

As a blogger constantly trying new looks, from a quiet luxury bob to romantic goth hairstyles, my hair gets a lot of heat. I needed this to play nice with my tools.

It absolutely does. It acts like a brilliant heat protectant. My hair dries faster, feels smoother, and has way more shine. There’s no residue or buildup, which is key for fine hair like mine.

Perfect for Achieving “Old Money Hair”

That chic, perfectly healthy, glossy look isn’t just about the cut. It’s about the hair quality. This infusion gave me that underlying shine and strength.

When I’d style loose waves or a sleek blowout, the hair just looked more expensive and cared-for. It’s the perfect base product for nailing that effortless, polished vibe.

Building Volume for Bigger Styles

I was worried a “treatment” might weigh my hair down. The opposite happened. Because it strengthens the hair at the root, I noticed less breakage and finer hairs snapping off.

This meant my hair actually felt thicker and could hold volume better. My go-to voluminous waves had more body and bounce from root to tip.

Protection for Frequent Heat Styling

If you’re into glitchy glam hair or any look that requires hot tools, protection is non-negotiable. This became my first line of defense.

My hair felt cooler to the touch after using my flat iron, a sign the serum was creating a barrier. The reduction in heat damage alone probably contributed to the retained length.

Does It Work on All Hair Types?

I have fine, straight-to-wavy hair. But I had two friends with very different hair test it. One has thick, curly hair; the other has a coily texture.

Both loved it. For curls, it defined them without crunch. For coily hair, it provided great slip for detangling and strong heat protection before blowouts. It’s a universal winner.

The Key Ingredients Breakdown

Let’s talk about what’s inside. Biotin is the star, known for supporting keratin infrastructure. But it’s not alone.

• Hydrolyzed Keratin: Repairs and fills in damaged spots on the hair shaft.
• Amino Acids: The building blocks of protein, they help fortify hair.
• Vitamin B5: Adds moisture and shine without grease.

How It Fits Into a Vampire Haircut

Edgy cuts like the vampire haircut or a shag need texture, but they also need health to avoid looking fried. This infusion gave me the perfect foundation.

My layers were piecey and defined, not brittle. The black hair color looked shinier and deeper, which is essential for that dramatic look.

Prepping for a Big Chop to a Lob

Thinking of going for an asymmetrical lob? You want your hair in its best health before a major cut. Using this for a month or two pre-chop strengthens the hair you’ll keep.

It ensures your new lob is swinging, shiny, and free of the old damaged ends, giving you a perfect fresh start.

Adding Shine to Romantic Goth Hairstyles

Romantic goth isn’t about matte, dry hair. It’s about lush, dark romance. Think soft waves with velvet ribbons.

This serum gave my dark hair a beautiful, subtle sheen that caught the light perfectly, making intricate braids and waves look luxe and intentional.

The Cost: Is It Worth It?

Let’s talk numbers. The bottle isn’t drugstore cheap, but it’s not astronomical for a high-quality treatment. One bottle lasted me nearly four months with regular use.

When you factor in that it replaces a separate heat protectant and a growth serum, it actually becomes very cost-effective. The results justified the price for me.

My Weekly Routine with Waves 18

Consistency is key. Here’s exactly how I fit it into my week. I don’t use it every single day, as my hair doesn’t need daily washing.

1. Wash hair 3 times a week (typically Mon, Wed, Fri).
2. Apply infusion to damp hair after each wash.
3. Style as usual with heat tools 2 of those 3 days.
4. On the 3rd day, let hair air-dry for a break.

Common Mistakes to Avoid

To get the most out of it, avoid these pitfalls. First, don’t apply it to soaking wet hair. Towel-dry first so it’s not diluted.

Second, don’t skip the scalp. Massaging it into the roots is crucial for the growth benefits. Third, a little goes a long way—you don’t need to drench your hair.

Pairing It With Other Products

This infusion layers beautifully. My favorite combo is this first, then a light mousse for hold, or a texturizing spray at the end.

I avoid using other heavy serums or oils with it, as that can overload the hair. It does enough on its own that you can simplify your routine.

Travel-Friendly? A Big Yes

The bottle is a perfect size for travel—not too big, not too small. The dropper locks securely, so I’ve never had a leak in my toiletry bag.

It’s my one must-pack hair product for trips, because it ensures my hair stays healthy even when I’m using a hotel dryer, which can be harsh.

Long-Term Health vs. Quick Fixes

This isn’t a magic potion for instant growth. It’s a long-term play for hair health. The growth is a side effect of having stronger hair that breaks less.

After six months, the difference in my hair’s density and resilience is what’s truly remarkable. It feels like I’ve been investing in my hair’s foundation.

Styling the Hime Cut with Strong Hair

A sharp hime cut with its straight, blunt lines demands hair that can hold a shape without frizz or flyaways. This infusion provided incredible smoothness.

My blunt bangs and long lengths dried perfectly straight with just a brush and dryer, holding that graphic, geometric shape all day.

For the Glitchy Glam Hair Aesthetic

Glitchy glam is all about imperfect, textured perfection. It often involves teasing or backcombing, which can be rough on hair.

Because this serum strengthens the hair, I felt more confident adding texture with my comb. My hair could take the manipulation without snapping.

The Final Verdict from Hailey & Team

So, does the Waves 18 Biotin Boost Infusion live up to the hype? In our experience, absolutely yes. It delivered on both its promises for us.

Our hair grew noticeably faster while becoming easier to style and healthier looking. It’s a staple we’ve all repurchased. It’s the workhorse product behind trying all the fun 2026 hairstyles trends.

So, that’s the full scoop on my experience. It wasn’t an overnight miracle, but a steady, noticeable improvement that made my hair feel like it could finally keep up with my style dreams.

If you’re tired of choosing between styling your hair and nurturing it, this product truly lets you do both. It takes the waiting out of wanting to try that new cut or look.

Your hair journey is personal, but sometimes the right tool just makes everything easier. This was that tool for me.
