Whether you choose to use essential oils or elastin for curl treatment, it mainly depends on the results you want to achieve and the type of perm you want to achieve:

While essential oils and elastin-based products can both benefit curly hair in different ways, they serve distinct purposes when it comes to perms or curl treatments.

Essential Oils:

• Essential oils, such as lavender, rosemary, jojoba, or coconut oil, are often used as a post-perm treatment to nourish, moisturize, and revitalize the hair. They can help to soothe the scalp and reduce inflammation caused by chemical treatments, while also restoring moisture to potentially parched hair. They do not create or define curls themselves but can enhance the health and bounce of existing curls.

For example, if you've just had a perm and want to maintain the health and vitality of your curls, using essential oils in a hair mask or as a leave-in conditioner can be highly beneficial.

Elastin-Based Products:

• Elastin is a protein found naturally in the human body that gives hair flexibility and elasticity. In hair care products, elastin is often included to improve the hair's resilience and ability to hold a curl pattern. Elastin-enriched perms or styling products can help create and maintain curls by improving the hair's texture and allowing it to return to its curled state after stretching.

If you're looking for a perm solution or a styling product to help set or hold a particular curl pattern, a product infused with elastin might be more appropriate. It can help give your curls a lasting definition and bounce, preventing them from becoming limp or lifeless.

In conclusion, the choice between essential oils and elastin would depend on your primary goal:

• For nurturing and maintaining the health of permed or naturally curly hair, choose essential oils.
• For creating or enhancing curl patterns and ensuring that they hold their shape, elastin-based products would be more suitable.

However, it's important to consult with a professional hairstylist to determine the best course of action based on your hair's unique needs and the type of perm you desire.
