Operating Instructions (Usage)
Follow these steps for optimal application of TRSTAY Pure Castor Oil:
- Prepare Hair: The oil can be applied to either damp or dry hair. For best absorption, some users prefer slightly damp hair.
- Dispense Oil: Squeeze the rubber bulb of the dropper to draw a small amount of oil into the pipette.
- Apply to Scalp: For scalp treatment, apply a few drops directly to the scalp. Use your fingertips to gently massage the oil into the scalp in circular motions.
- Apply to Hair Strands/Ends: For hair conditioning, apply a few drops to the palms of your hands, rub them together, and then distribute evenly through the hair strands, focusing on areas that need extra attention, such as dry ends.

Maintenance
To ensure the longevity and efficacy of your TRSTAY Pure Castor Oil:
- Storage: Store the bottle in a cool, dry place, away from direct sunlight and extreme temperatures. The amber glass bottle helps protect the oil's potency from light degradation.
- Cleaning the Dropper: If the dropper becomes clogged or dirty, rinse it with warm water and allow it to air dry completely before reinserting it into the bottle.
- Cap Security: Always ensure the cap is tightly secured after each use to prevent contamination and evaporation.
Troubleshooting
Here are some common questions and solutions regarding the use of TRSTAY Pure Castor Oil:
- Oil appears cloudy or has changed consistency: Castor oil can sometimes solidify or become cloudy in cold temperatures. This is normal and does not affect its quality. Gently warm the bottle in a bowl of warm water (do not microwave) to return it to its liquid state.
- Dropper is not dispensing oil: Ensure the dropper is fully submerged in the oil when squeezing the bulb. If it's clogged, clean it as described in the Maintenance section.
- Skin irritation after use: Discontinue use immediately. Perform a patch test on a small area of skin before full application to check for sensitivity.
- No noticeable results: Hair growth and strengthening take time. Consistent use over several weeks or months is often required to see visible improvements. Ensure you are applying it as directed.
