I'm not looking for a miracle to grow all my hair back. I just wanted to keep what I have. I thought GrowOUT was working, and my girlfriend confirmed it. Even she noticed that it's working! And, to my surprise, some of it IS growing back. Let me buy more now!

I'm almost 60, and my hair is so thick I have trouble getting my fingers around my hair when I put it in a ponytail! I haven't had this wonderful problem since I was a teenager! Plus, the new hairs around my hairline make me smile every time I look in the mirror! Thanks, Alan & Cheryl for inventing Belegenza!

Hi Alan & Cheryl, I just want to let you know how much I love your products. I don't know if you knew that I was diagnosed with Valley Fever and had a rough two years. I was on such heavy duty medications that my hair was falling out in big patches. It was so bad that I had to wear a bandana to cover it. After using your products for the past year and a half, I am happy to say my hair has grown in beautifully and no need for bandanas!

I totally beat my sorority sisters at growing our hair out this past year. I chopped my hair off last September, and was growing it back, and then started using Growout exclusively since February, and in the 10 months, I’ve grown over 7 inches and it’s shiny and healthier than ever. That’s crazy! That’s like 3/4 inch a month, but I know it’s more since February. I should have measured because I can tell it seems to be more than 3/4 inches per month!

I used your system a couple years ago following my chemotherapy. I never lost my hair completely as my treatment was considered mild. I was pleased with the results but went back to my old shampoo after my hair seemed to recover. Slowly my hair has seemed to thin again, not as bad as during chemo but it’s definitely not like it was after chemo stopped & I had been using your products.

The Simply Smooth Humidity Blocker is the perfect product for you! Here's why...

Keep Your Style Looking Like Your Style

You finish styling your hair, step outside, and notice the change: flyaways appear, smooth lengths begin to swell, or curls lose their definition.

Moisture in humid air can change the way your hair behaves. We created Simply Smooth Humidity Blocker to help you maintain a smoother, more manageable finish while keeping softness and natural movement.


Is This Product Right for You?

  • Your hair becomes frizzy or puffy in humid weather.
  • Your straight styles lose their smooth finish after you leave home.
  • Your waves or curls need definition with less visible frizz.
  • Your color-treated or chemically processed hair feels difficult to smooth.
  • You’re looking for humidity control without a stiff finish.
  • You’ve been searching for a silicone-free smoothing product.

Why Hair Fitnessâ„¢ Matters

Hair Fitnessâ„¢ is our philosophy of caring for hair through thoughtful, consistent habits.

It begins with a clean, comfortable scalp and continues with appropriate conditioning, gentle detangling, and careful styling.

Preparation influences performance. When your hair is evenly conditioned and your styling product is evenly distributed, you build a stronger foundation for your finished style.

Simply Smooth fits into that preparation, helping you manage frizz before it becomes the focus of your day.


Why This Product Works

Hair responds to moisture in the air. Depending on its texture and condition, that response can show up as swelling, flyaways, or a change in your finished shape.

We designed Simply Smooth to add humidity resistance and conditioning support in a single styling step.

Its formula combines moisture-supporting ingredients, marine extracts, and emollients to help hair feel smoother and more manageable. The goal is a polished finish that stays flexible.

Even application matters. Working in sections helps you smooth the lengths that need it instead of concentrating product in one spot.


What You May Notice

With consistent use and an amount suited to your hair, you may notice:

  • Less visible frizz and fewer flyaways
  • Smoother-looking lengths in humid conditions
  • Waves and curls with a more defined appearance
  • Softer-feeling ends
  • A more polished finish with natural movement
  • Hair that is easier to arrange and manage

How to Use

  1. Apply a small amount to clean, damp hair.
  2. Distribute evenly through the mid-lengths and ends.
  3. Work through sections as needed for thorough coverage.
  4. Blow-dry for a smoother style or diffuse to encourage curl definition.
  5. Use lightly on dry hair for touch-ups.

Simply Smooth can be used daily as needed. Adjust the amount to your hair’s length, density, texture, and condition.

Professional Tip

Apply Simply Smooth before you begin drying, focusing on the sections where frizz usually appears first.

For a smooth blowout, guide the airflow down the hair while using your brush to shape each section. For curls, handle the hair gently as you diffuse. Product distribution and styling technique work together to support a more consistent finish.


Smooth Blowouts and Defined Curls

Humidity control can support different styling goals.

For a straighter finish, we recommend applying evenly before blow-drying and working through manageable sections.

For waves and curls, distribute through damp lengths, shape your natural pattern, and diffuse gently.

On dry hair, use a small amount to refine individual areas rather than layering it over the entire style repeatedly.


Clean Beauty Standards

Every bottle of Simply Smooth Humidity Blocker is thoughtfully formulated with carefully selected ingredients that support smoothness, softness, and everyday manageability.

  • Silicone-Free
  • Paraben-Free
  • Phthalate-Free
  • Petrolatum-Free
  • Lightweight Styling Formula

We focus on humidity control to keep hair flexible and comfortable to style.


What’s Inside—And Why It Matters

Red and Brown Seaweed Extracts

Help condition hair for a smoother, more supple feel.

Castor Seed Oil

Helps soften rough-feeling lengths and ends.

Glycolic Acid

Contributes to the formula’s acidity and surface-conditioning approach.

Glycerin and Sorbitol

Help attract moisture to support hydrated-feeling strands.

Hydrolyzed Wheat Protein

Fatty Alcohols

The Belegenza Difference

We’re Alan & Cheryl, brother and sister and founders of Belegenza. We created our hair care around a simple idea: beautiful hair deserves thoughtful care at every step.

Our approach brings carefully selected ingredients together in silicone-free formulas, with attention to both scalp care and the condition of your strands.

That’s why we teach Hair Fitness™. A clean foundation, appropriate conditioning, gentle handling, and consistent habits all contribute to healthier-looking hair.

Simply Smooth brings that philosophy into humidity-conscious styling, helping you maintain a polished finish while preserving softness and movement.

The condition of your hair reflects what you repeatedly do—not just what you occasionally do.


Disclaimer

Your hair’s natural texture, starting condition, styling technique, and the weather influence your results. Simply Smooth supports cosmetic smoothness and humidity resistance. If you have known ingredient sensitivities, review the product’s full ingredient list before use.


Frequently Asked Questions

What does Simply Smooth Humidity Blocker do?

We designed Simply Smooth to help reduce visible frizz and support smoother-looking styles in humid conditions. It also provides conditioning support so hair feels soft and manageable.

How do I use Simply Smooth for frizz control?

Apply a small amount to clean, damp mid-lengths and ends, then distribute evenly before styling. Work in sections when needed so the areas most prone to frizz receive consistent coverage.

Can I use Simply Smooth on curly or wavy hair?

Yes. Distribute through damp hair, gently shape your waves or curls, and diffuse for definition. Adjust the amount to suit your texture and density.

Is Simply Smooth suitable for fine hair?

Yes. We recommend beginning with a small amount, focusing on the lengths and ends. Distribute thoroughly before deciding whether you need more.

Can I apply Simply Smooth to dry hair?

Yes. Use lightly on dry hair to smooth flyaways or refine areas that need a touch-up. Start with a small amount and apply only where needed.

Can I use Simply Smooth on color-treated hair?

Yes. You can include Simply Smooth in the styling routine for color-treated or chemically processed hair that needs help with smoothness and manageability.

Yes. We designed Simply Smooth to provide smoothing and humidity-control support without silicones.

Will Simply Smooth straighten my hair?

Simply Smooth helps you create a smoother finish, but your styling technique determines the shape. Use a brush and blow dryer for a straighter look, or diffuse to maintain waves and curls.

Can I use Simply Smooth every day?

Yes, as needed. Adjust how much you apply according to your hair’s condition and whether you are styling damp hair or touching up a dry style.

My girlfriend commented on how thick my hair is now and asked what I was using. I think she will now start using Belegenza also. Just wanted you to know how much I love your products and glad you are doing so well.
