FAQs
How does Leave-In Conditioner differ from Blow-Out Creme and Curly Creme?
Both products aim to improve overall hair and skin health, but they serve slightly different purposes and offer different benefits:
Leave-In Conditioner:
- Primary Function: This product is designed mainly to detangle hair and provide lightweight hydration.
- Additional Benefits: It also offers protection against heat, pollution, and UV rays, which helps prevent damage and maintain hair health.
- Use: Leave-in conditioners are generally used on damp hair and left in without rinsing. They focus on hydration and making hair easier to manage.
Blow-Out Creme and Curly Creme:
- Primary Function: These products are primarily styling aids: Blow-Out Creme adds body, bounce, and shine to the hair, while Curly Creme defines curls without leaving them with a crunchy feeling. Additional Benefits: They both provide protection against UV rays, pollution, and heat (up to 450º F), which helps maintain the hair's integrity during styling.
The Leave-In Conditioner is more about detangling and prepping the hair while providing lightweight hydration with added protection, while the Blow-Out and Curly Creme focuses on achieving specific styling goals with added protection against environmental and heat damage.
If I'm already using Blow-Out Creme or Curly Creme, should I add Leave-In Conditioner to my routine, or substitute it?
Leave-In Conditioner detangles and preps your hair before styling.
Will layering Leave-In Conditioner with any of the other styling products provide additional benefits or additional heat protection?
The Leave-In Conditioner helps to detangle and add lightweight hydration (not hold like the Styling Creme). It has heat protection up to 450º F and does not provide more heat protection beyond that.
Should I use Leave-In Conditioner and Magic Serum together? Which of the two is better at preventing frizz?
Leave-In Conditioner and Magic Serum can be used cocktailed together on damp hair (before styling) to achieve shiny, soft, smooth hair with less frizz. Magic Serum can also be used on dry hair on extra flyaways or split ends. Both products are also proven to reduce hair breakage.
Leave-In Conditioner
- Reduces breakage by up to 76% after a single use*
*Repeated grooming study with 10 bleached hair tresses, compared to control.
Magic Serum
- Reduces breakage by up to 81% after a single use*
*Repeated grooming study with 10 bleached hair tresses, compared to control.
If you have fine hair, you may benefit from just using the Leave-In Conditioner first on damp hair and the Magic Serum on dry hair.
