Designed for Control. Built for Real Working Techs.

They’re tool problems.

Builder gel flooding.

Hard gel uneven edges.

Polygel inconsistent shaping.

Often, the issue isn’t the product.

It’s using one generic brush for everything.

Control requires intention.

Intention requires the right geometry.

SHi® brushes were designed with proper working dimensions, including a true 11mm length for balanced pressure and smoother control.

Not decorative sizes.

Not generic shapes.

Purpose-built tools for daily professional use.

Builder gel is self-leveling, but it still requires guidance.

The rounded head allows you to:

• Distribute gel evenly

• Float product toward the cuticle with control

• Reduce surface disruption

• Maintain smooth overlays

Round geometry supports flow.

Flow supports consistency.

Length changes leverage.

This brush features a true 11mm working length, intentionally selected to:

• Improve balance in the hand

• Reduce excess downward pressure

• Support smoother gel control

Short brushes increase force.

Balanced length improves precision.

Most techs clean their brushes but very few protect them the right way.

Your brush is your #1 tool, but it’s fragile: leftover gel will ruin it faster than you think.

That’s why I designed the SHi® Ultimate Gel Brush Care Guide— a complete instruction that teaches you how to clean daily, condition monthly, and store properly between every client.

✅ Keep brushes soft & flexible

✅ Dissolve leftover gel — between clients or sets

✅ Save time, money, and frustration

✅ PROTECT your most valuable tool

It’s the same method I teach my Masterclass students, and the same system I use every day.

"Protect your tools. They’ll take care of your work and your clients will notice the difference."

— Tom Nguyen, Mr. SHi

Saving gel brushes around the world

I see this all the time — nail techs stuck with hardened brushes between clients because no one taught them the right care system.

Here are 3 common mistakes and how to avoid them:

1️⃣ Leaving leftover gel behind

2️⃣ Pulling hardened product with hands

3️⃣ Storing improperly

Most brush damage doesn’t happen during your set, it happens in the moments between clients. With the right daily habits and pro-level care system, you can protect your Kolinsky brush for years, not months.

Why most brushes get ruined:

• Leftover gel hardens inside

• Cheap painted handles crack

• Improper storage

• No conditioning means brittle, frayed bristles

Your builder gel brush is your most valuable tool but most techs ruin it without realizing why:

❌ Hardened Gel

❌ Over-cleaning with solvents

❌ No conditioning after cleaning

❌ Brittle, frayed bristles after a few months

1️⃣ Clean gently after use according to your gel system

Do not allow gel to cure in the bristles.

After finishing application:

• Gently wipe excess product with a lint-free wipe
  
• Use your gel system’s recommended cleanser if needed
  
• Keep bristles aligned while cleaning
  

Dried gel inside the brush shortens lifespan and affects control.

2️⃣ Avoid acetone soaking

Acetone can:

• Weaken bristle bonding
  
• Damage brush structure
  
• Affect long-term performance
  

These brushes are designed for gel systems, not soaking removal.

3️⃣ Reshape bristles after use

After cleaning:

• Lightly reshape the bristles

Store protected to maintain edge precision

• Store flat or upright with bristles protected
  
• Avoid crushing inside drawers or tight containers

4️⃣ Use Dedicated Brushes for Different Gel Types

Builder gel, hard gel, and polygel behave differently.

Using separate brushes:

• Prevents cross-contamination
  
• Maintains performance consistency
  
• Extends overall lifespan
  

This is why many professionals keep a dedicated brush per gel system.

5️⃣ Replace Without Hesitation — Remember: clients notice your tools

Even well-maintained brushes wear over time.

When you notice:

• Fraying
  
• Loss of structure
  
• Reduced control
  

Replace it.

A fresh brush improves results instantly.

Professional tools are meant to work hard and be replaced responsibly.

That’s why I created the SHi® Complete Builder Gel Brush Care Guide, designed to clean, hydrate, and protect your brush, so it stays soft, flexible, and high-performing year after year.

✅ No more stuck brushes

✅ Save $$$ on replacements

✅ Keep your brushes performing like new

Protect Your Control. Extend Your Tool.

A gel brush is not just an applicator.

It is a precision instrument.

Proper care protects the bristles, maintains balance, and keeps application consistent.

How to Store & Choose Your Builder Gel Brushes Like a Pro

Most techs only think about cleaning — but how you store and choose your brush handle is just as important.

✔️ Store your brush downward — This stops leftover monomer from running into the ferrule or handle — which can swell, crack, or ruin your brush.

✔️ Never lay your brush flat or bristles up — it traps liquid inside.

✔️ Avoid cheap plastic or painted handles (especially black, green, or printed logos). Monomer breaks these down fast — the paint chips, the plastic cracks, and your brush looks unprofessional in front of clients.

✔️ Choose acetone-resistant handles — high-quality wood or sealed finishes designed for pro use.

🗝️ Remember: Skill gets you clients, but clean, well-kept tools keep them loyal.

Proper storage is just as important as proper cleaning.

When you leave leftover gel in your brush, gravity can pull that liquid into the ferrule — or worse, down into the handle — causing swelling, cracking, or paint peeling.

That’s why I recommend this professional method:

✔️ Use the SHi® Silicone Brush Clip to hold your brush downward — with the bristles pointing toward the table.

✔️ This prevents leftover gel from running into the ferrule or handle.

✔️ It also keeps your bristles shaped, clean, and ready for the next client.

✅ Prevents hidden damage: Most brushes crack from the inside out when monomer seeps in.

✅ Protects your health: You only touch the clean brush handle — not dirty bristles. This reduces the risk of contact dermatitis or overexposure.

✅ Professional impression: Clients judge your work by the tiny details. A brush stored properly — with no visible residue — builds trust. Skill gets you clients, but your professional aesthetic keeps them loyal.

✅ Longer lifespan: Storing your brush downward helps extend both the bristles and the handle life — saving you money.

✔️ Invest in a high-quality, acetone-resistant handle or properly sealed materials designed for salon use.

✔️ Care for it with daily cleaning

✔️ Treat your brush like the investment it is — it will serve you for years.

"Your tools take care of your work. You take care of your tools."

With the SHi® Ultimate Brush Care Guide, you have everything you need:

✅ Daily cleaning

✅ Monthly conditioning

✅ Proper downward storage clips

✅ And the brush that will stay strong, balanced, and professional — just like you.
