Quality Control

Full Ridge Hair · Quality Control

Made With Intention.
Documented With Care.

Every bottle is produced against a written batch record — the same documentation standard used by professional cosmetic manufacturers. Here's exactly what that looks like.

Our Standard

Why We Document Every Batch

Most small-batch hair oils are made without any formal record-keeping. Ingredients are eyeballed, batches aren't tracked, and there's no way to trace a problem back to its source if one arises.

We do it differently. Before the first drop goes into a bottle, we complete a 12-section production record covering everything from scale calibration and ingredient lot numbers to scent evaluation, fill consistency, and final sign-off. That record stays on file for every batch we produce.

It's not required of us at this scale. We do it because it's the right way to make something that goes on your body.

01
Ingredient Traceability
Every batch records supplier name and lot number for all three ingredients.
02
Precision Weighing
Digital scale accurate to 0.01g. Calibrated before and after every production run.
03
Sanitation Protocol
All equipment cleaned with isopropyl alcohol. Nitrile gloves worn throughout.
04
Sensory Evaluation
Scent checked twice — immediately after mixing and after a 30-minute rest.
05
Bottling QC
Every bottle inspected for fill level, cap seal, label alignment, and clarity.
06
Batch Sign-Off
No bottles enter inventory without a completed record and producer signature.
The Formula

Standard 1L Batch — ~16 Bottles

Three ingredients. No fillers, no fragrance, no carrier oil filler stretching the formula. The ratios are fixed — any deviation from the standard formula is documented and must be approved before the batch ships.

Ingredient (INCI Name) Volume % of Batch Target Weight Supplier
Ricinus Communis (Castor) Seed Oil 945 ml 94.5% 945.0 g Jedwards
Rosmarinus Officinalis (Rosemary) Leaf Oil 30 ml 3.0% 27.6 g Jedwards
Cedrus Virginiana (Cedarwood) Wood Oil 25 ml 2.5% 23.3 g Jedwards
Total 1000 ml 100% ~995.9 g
Production Process

What Happens on Every Production Day

The batch record walks through 12 sections from pre-production checks through to final sign-off. Here's the arc of a standard production run.

01
Equipment sanitation
All glass equipment wiped down with isopropyl alcohol. Bottles inspected for cracks, residue, or defects. Work surface cleaned.
02
Ingredient checks
Color and clarity of castor oil confirmed. Rosemary and cedarwood scent evaluated. All expiry dates verified in range.
03
Scale calibration
Digital scale (0.01g accuracy) calibrated with calibration weight before production. Drift re-checked after the batch is complete.
04
Precision weighing
Castor oil weighed first into the main beaker. Each essential oil weighed individually into separate vessels, then transferred and rinsed into the beaker. Actual weights logged at every step.
05
Mixing and rest
Oils stirred minimum 3 minutes with glass rod — no plastic. Batch rested minimum 5 minutes. Scent evaluated twice before bottling is approved.
06
Bottling QC
Target fill 59ml per 2oz bottle. Each bottle checked for fill level, cap security, label alignment, absence of bubbles or cloudiness, and dropper seating.
07
Batch sign-off
Completed record reviewed. Any deviations documented with corrective action. Producer signature and date required before inventory is released.

We're a small operation. One founder, one formula, one supplier. The batch record exists because every bottle should be traceable — if there's ever a quality issue, we can identify exactly which batch it came from, which ingredients were used, and what the production conditions were. That's what accountability looks like at our scale.
