Salon Developer Comparison: THE OX, Sroloc OX and TIERS Developer
A developer (2nd agent) is used in almost every colour service, so differences in viscosity, mixing behaviour and finish can affect how smoothly the work goes. With material costs under review in many salons, the second agent is often one of the first items compared.
This compact comparison looks at three Japan-made developers stocked at Beauty Garage Singapore — HAIR STANDARD THE OX, Sroloc OX and TIERS Developer — by texture, formulation and everyday handling.

Quick Comparison at a Glance
Viscosity, silicone content, care ingredients and pH differ across the three developers. The table below summarises the main points for the 6% (20 Vol) versions.
Mixing ratio is determined by the color (1st agent) you pair the developer with — follow the instructions supplied with that product.
The Three Developers in Detail
HAIR STANDARD THE OX 2000 mL
A silicone-based developer with a medium, emulsion-type viscosity that sits between the firmer and the more fluid options in this comparison. The application feel is smooth but lighter than Sroloc OX, and it mixes and spreads with little resistance.
- Texture: Medium viscosity, emulsion type
- Handling: Mixes easily and spreads smoothly on the hair
- Formulation: 7 care ingredients and 2 pH adjusters, pH around 3
- Daily-use fit: A straightforward everyday option for salons wanting a middle-ground texture
Useful as a general-purpose second agent for salons that find firmer developers heavy and thinner ones difficult to control.
Sroloc OX 2000ml
A silicone-based developer with a medium to slightly firmer viscosity and a heavier application feel. It mixes easily and holds its body in the bowl, which some colourists prefer when working section by section.
- Texture: Medium to slightly firm
- Handling: Mixes easily; slightly heavier, more substantial application feel
- Formulation: Silicone base with Ethylhexyl Palmitate, pH 2.9 – 4.5
- Daily-use fit: A long-running staple of the Sroloc colour range in Japan
Suited to salons that prefer a developer with more body during application.
TIERS Developer 2000ml
A silicone-free developer with a noticeably looser, more watery texture. It carries the widest ingredient list of the three, including 11 botanical extracts, hyaluronic acid and NMF-type moisturising components.
- Texture: Loose and watery
- Handling: Thinner consistency takes more care when mixing and applying
- Formulation: Silicone-free, with botanical extracts, keratin and silk components, pH 2.5 – 3.5
- Daily-use fit: Useful for salons prioritising a silicone-free, moisture-focused formulation
A practical choice where ingredient content matters more than body in the bowl.
At a Glance: Which Developer Suits Which Preference?
- For a middle-ground texture that is neither heavy nor watery: HAIR STANDARD THE OX
- For a firmer, more substantial application feel: Sroloc OX
- For a silicone-free, ingredient-rich option with a fluid texture: TIERS Developer
Developer preference comes down to mixing, application, spread and how the colour develops in each salon's own workflow, so trialling more than one type is often the clearest way to decide.
Conclusion
All three developers cover standard colour work in both 6% and 3%; the difference is in texture and formulation. Cost efficiency matters, but so does how a developer handles at the chair and how the finish turns out — so it is worth comparing on both.
