Hair sealing is the process of applying a heavy, thick oil to the hair to create a barrier that helps prevent moisture from escaping. This barrier acts like a seal, locking in hydration.
Essentially, it's about:
- Creating a Barrier: The oil forms a protective layer on the hair shaft.
- Retaining Moisture: This barrier reduces moisture loss, keeping hair hydrated.
However, it's crucial to moisturize your hair before sealing. Since the oil barrier also prevents moisture from entering, sealing dry hair can lead to further dryness.
Think of it like this: you need to "fill" your hair with water (moisture) first, and then use the oil to "trap" it inside.
Here's a breakdown of the process and considerations:
The Importance of Moisturizing First
Sealing isn't a replacement for moisturizing; it's a complement. Here's why moisturizing beforehand is essential:
- Addressing Dryness: Moisturizing provides the initial hydration that dry hair needs.
- Optimizing Sealing: Sealing moisture into already-hydrated hair maximizes the benefits.
Types of Sealing Oils
Common oils used for sealing include:
- Coconut oil
- Shea butter
- Castor oil
- Grapeseed oil
- Avocado oil
These oils are typically heavier and thicker than oils used for moisturizing.
Best Practices for Hair Sealing
- Moisturize: Use a water-based moisturizer or leave-in conditioner.
- Apply Oil: Apply a small amount of your chosen sealing oil to your hair, focusing on the ends.
- Style as Usual: Proceed with your regular styling routine.
Hair sealing is a technique to retain moisture in your hair by creating a barrier with a heavy oil after hydrating it, helping to prevent dryness and improve overall hair health.
