Applying heat can help hair absorb treatments like dye more effectively by opening the hair cuticle. Here's how to process hair with heat at home safely:
Understanding the Process
Applying heat helps to lift the hair's cuticle, allowing treatments (like dye, deep conditioners, or hair masks) to penetrate the hair shaft more deeply. This can result in more vibrant color, better conditioning, or improved product absorption. However, excessive heat can damage hair, so it’s crucial to use it carefully.
Methods for Applying Heat
-
Hair Dryer:
- This is the most common method.
- How to: Apply the hair treatment as directed. Then, use your hairdryer on a low or medium heat setting. Direct the heat evenly around your head, holding the dryer a few inches away from your hair to avoid direct heat damage. Keep the dryer moving. Do not overheat one spot. Heat for the recommended time.
- Pros: Readily available, good for even heat distribution.
- Cons: Can be drying if used on high heat.
-
Steamer:
- A hair steamer uses moist heat to open the hair cuticle.
- How to: After applying your chosen treatment, sit under a hair steamer, according to the steamer’s instructions. The steam will help lift the cuticle and allow the product to penetrate.
- Pros: Hydrating, gentle.
- Cons: Requires a dedicated steamer appliance.
-
Heated Cap:
- Heated caps come in two main types: electric and microwaveable.
- How to (Electric): Apply the hair treatment. Place a plastic cap over your hair. Place the heated cap over the plastic cap. Turn on the cap to the low or medium setting. Keep on for the recommended time.
- How to (Microwaveable): Follow the microwave instructions provided with the cap. Heat it only as recommended to avoid burns. Apply treatment, cover with a plastic cap and then the heated cap.
- Pros: Portable, relatively inexpensive, provides consistent heat.
- Cons: Can overheat if not used properly; electric caps require a power source.
-
Warm Towel:
- A simple and effective method for deep conditioning treatments.
- How to: Soak a towel in hot (but not scalding) water. Wring out the excess water. Apply your hair treatment. Wrap your hair with the warm towel. Re-warm the towel as needed during the processing time.
- Pros: Simple, inexpensive, hydrating.
- Cons: Heat dissipates quickly.
Important Considerations:
- Read product instructions: Always follow the specific instructions provided with your hair dye, deep conditioner, or hair mask. They may have specific recommendations regarding heat processing.
- Use low to medium heat: Avoid high heat settings, as they can damage your hair.
- Protect your hair: Always use a plastic cap or towel between your hair and the heat source to protect it from direct heat damage.
- Monitor your hair: Check your hair periodically during the heat processing to ensure it is not overheating or becoming damaged.
- Adjust time: It is better to go for shorter bursts of heat than to apply continuous heat. Remove the heat source or allow the hair to cool before reapplying.
- Hydrate: Always follow heat treatments with a hydrating conditioner or deep conditioner to replenish moisture.
