Private Label 150ml Hair Oil Bottle: 8 Stainless Steel Beads & Rotating Comb Cap

Generic squeeze bottles no longer capture consumer attention. Today's buyers seek tools that merge application, massage, and dispensing into one seamless experience.

Enter the 150ml Hair Oil Bottle with 8 Stainless Steel Beads—a private label solution that transforms a standard hair oil container into a scalp therapy device. With a rotating comb cap, PE/HDPE construction, and customizable finish options, this bottle is engineered for hair oils, serums, scalp treatments, and even styling colors.

This article breaks down every specification—from the 50mm diameter to the 8 steel beads—and explains why this packaging is gaining traction among private label brands.

Product Overview: More Than a Bottle

At first glance, this is a 150ml cylindrical container. But look closer. The cap is not a simple screw-top. It houses a PP comb that rotates open to reveal 8 stainless steel beads. This dual-function design serves two purposes:

Dispensing: The beads roll against the scalp, distributing oil evenly without dripping.

Massage: The cool steel beads provide gentle acupressure, stimulating blood circulation during application.

Why 150ml? The "Goldilocks" Capacity for Hair Oils

Hair care consumers face a dilemma: Travel-sized bottles (50-100ml) run out too quickly, while jumbo sizes (300ml+) are heavy and degrade before use. The 150ml bottle hits the sweet spot.

For Daily Users: Lasts 4-6 weeks with regular application.

For Salons: Large enough for professional use but small enough for retail shelves.

For E-commerce: Compliant with standard shipping weight limits (under 200g filled).

The 50mm diameter offers a comfortable grip. Unlike narrow 35mm bottles that strain the hand, this wider body fits naturally in the palm, allowing controlled squeezing even when hands are oily.

Material Science: HDPE Bottle + PP Cap

HDPE (High-Density Polyethylene) for the Bottle

HDPE is the workhorse of cosmetic packaging, and for good reason:

Chemical Resistance: Unaffected by oils, essential oils, silicones, and alcohols found in hair serums.

Lightweight: Reduces shipping costs compared to glass.

Squeezable yet Sturdy: Flexible enough to dispense thick formulas but rigid enough to stand upright on shelves.

Recyclable: HDPE is #2 plastic, widely accepted in curbside recycling programs.

Important note: The spec sheet allows for PE (Polyethylene) customization. PE and HDPE are closely related, but HDPE offers better rigidity. If your formula is very thin (e.g., pure argan oil), standard PE may be too soft—stick with HDPE.

PP (Polypropylene) for Cap and Comb

The rotating cap and integrated comb are molded from polypropylene. PP offers three advantages for this application:

Flexural Fatigue Resistance: The "rotate to open" mechanism requires a material that won't crack after hundreds of twists. PP excels here.

Heat Resistance: PP withstands autoclaving (sterilization) if needed for professional salon use.

Non-Toxic: Food-grade safe; no risk of leaching into the oil.

The Roller Beads: 8 Stainless Steel Balls (Customizable)

The standout feature of this bottle is the 8 stainless steel beads embedded in the dispensing head. Here is why steel beats plastic every time.

Steel vs. Plastic Roller Balls

Customer perception matters: A steel roller ball signals "salon quality" and "therapeutic tool." Plastic signals "sampler" or "travel item."

Why 8 Beads?

Most competitor bottles use 3 or 4 beads. The 8-bead configuration creates a wider massage surface. Instead of a single line of oil, the user gets a broad stripe that covers more scalp per pass. This is especially valuable for:

Scalp treatments: Covering the part line efficiently.

Thick hair: Pushing oil through dense strands to reach the scalp.

Bald/Shaved heads: Full coverage with minimal passes.

Customization Options

The spec sheet notes: "Bead material can be customized."

Standard: Stainless steel (recommended for most hair oils)

Alternative: Glass beads (heavier, smoother, but more expensive and breakable)

On request: Ceramic or jade (for "crystal" or "wellness" branding)

Rotating Comb Cap: Application Reimagined

The comb is not an add-on. It is integrated into the cap via a rotate-to-open mechanism.

How It Works

Closed position: The comb is nested inside the cap. No oil escapes. The bottle looks like a standard container.

Rotate to open: Twist the comb 90 or 180 degrees. Internal channels align, allowing oil to flow from the bottle into the comb's teeth.

Application: Squeeze gently. Oil travels through the comb and onto the scalp, while the stainless steel beads massage simultaneously.

Close and store: Rotate back to sealed position. No mess, no leaks.

PP Comb Material

The comb is molded from polypropylene. While PP is not as premium as metal or acetate combs, it offers:

Flexibility: Teeth bend rather than break if dropped.

Chemical resistance: Won't swell or soften from oil exposure.

Easy molding: Allows fine tooth spacing (ideal for parting hair).

Pro tip for brands: If your positioning is ultra-luxury, ask your supplier about overmolding the comb with soft-touch TPE or offering a removable metal comb insert.

Matte vs. Glossy Finish: What Your Brand Needs

The bottle finish is customizable between matte and glossy. This is not just aesthetic—it affects perception and functionality.

Our recommendation: Choose matte for hair oils. Oily fingerprints are inevitable. A matte finish conceals them. Glossy bottles on a retail shelf look smudged within minutes.

Suitable Formulas: What Can You Fill This With?

The spec sheet lists: hair care product: conditioner, shampoo, styling color, scalp care. But realistically, this bottle is optimized for low-to-medium viscosity liquids.

Best Formulas

Avoid These Formulas

Private Label Customization Options

As a private label solution, this bottle offers several branding opportunities.

1. Bottle Color

Natural (translucent) – Shows oil level

White or Black – Classic, clean

Custom amber, cobalt, or green – For "natural" positioning

2. Labeling Area

The 50mm diameter provides a generous front-and-back label panel. Because the bottle is cylindrical (not oval), use shrink sleeves for 360-degree graphics or pressure-sensitive labels for front/back placement.

3. Finish as Mentioned

Matte or glossy surface treatment.

4. Bead Material Substitution

Swap steel for glass, ceramic, or jade to differentiate your brand.

5. Comb Color

The PP comb can be molded in any color. A contrasting comb (e.g., black comb on a white bottle) signals "premium detail."

Manufacturing & Quality Considerations

Filling the Bottle

Because this bottle has a complex cap with internal channels, filling is typically done with the cap removed. Standard piston fillers work well. The 150ml capacity and 50mm neck opening accommodate most filling nozzles.

Important: After filling, the cap must be placed in the "closed" (non-flow) position before shipping. Otherwise, oil will leak during transport.

Leak Testing

The rotating seal is the most common failure point. Request vacuum leak testing (ASTM D3078) on your first production run. Fill 30 bottles, invert them for 24 hours, and check for any oil migration past the rotating mechanism.

Material Compatibility Testing

If your hair oil contains essential oils (e.g., peppermint, tea tree, rosemary), test for stress cracking in HDPE. Some terpenes cause environmental stress cracking. Accelerated aging studies (40°C / 75% RH for 4 weeks) will reveal any issues.

Positioning & Marketing Angles for Your Brand

Once you private label this bottle, here is how to sell it:

Angle 1: "Scalp Massager + Oil Dispenser in One"

"Why apply oil with your fingers when you can massage and dispense simultaneously?"

Angle 2: "8 Cooling Steel Beads for Circulation"

"Stainless steel retains coolness. Each application feels like a spa scalp treatment."

Angle 3: "No More Drippy Bottles"

"Rotate to open. Apply. Rotate to close. Zero mess."

Angle 4: "150ml – The Perfect Size for Results"

"Large enough to see transformation. Small enough to finish before oxidation."

Comparison: This Bottle vs. Standard Hair Oil Packaging

Final Verdict: Who Should Buy This Bottle?

This 150ml hair oil bottle with 8 stainless steel beads and rotating comb cap is ideal for:

Private label brands launching a premium hair oil line

Scalp care specialists (anti-hair loss, dandruff, growth serums)

Salons selling take-home products with "professional tool" positioning

E-commerce brands looking for a packaging differentiator

It is not for:

Extremely thick formulas (use a jar or wide-mouth tube)

Budget-focused brands (the complex cap costs more than standard closures)

Technical Summary for Procurement Teams

Next Steps: Sourcing This Bottle

When contacting a supplier (like LISSON, as noted in your image), request:

A physical sample – Test the rotate mechanism and bead smoothness.

Material certificates – Confirm HDPE and PP are food/pharma grade.

Leak test data – For the rotating seal.

MOQ (Minimum Order Quantity) – Typically 5,000–10,000 units for custom colors.

Lead time – Usually 30–45 days for molded bottles.

Invest in this packaging, and your hair oil will no longer compete on formula alone. It will compete on experience—and the 8 stainless steel beads will win that battle every time.
