Скачать или смотреть Why Type 4 Hair Can't Be Treated Like Straight Hair on Wash Day - It's Structural (Part 1)

Are rinse-out conditioners and deep conditioners actually different - or is it just marketing? In this first presentation of my conditioner series, we're breaking down the science of conditioning for type 4 hair using hair fiber research and formulation principles.

In this PowerPoint discussion, I explain what really happens to the hair strand when you apply a rinse conditioner versus a deep conditioner. We'll explore how conditioning agents deposit onto the cuticle, how heat affects diffusion into the fiber, and why contact time matters -- especially for kinky and coily hair.

If you've ever wondered:
Do deep conditioners penetrate deeper than rinse-out conditioners?
Is heat necessary for deep conditioning?
Does a rinse conditioner "close the cuticle"?
How do cationic surfactants actually work on type 4 hair?
Is deep conditioning really needed every wash day?

This video will give you the structural and formulation science behind it.

In this presentation, we cover:
The structure of type 4 hair and why friction matters
Cationic conditioning agents and how they bind to the hair fiber
Surface lubrication vs internal plasticization
The role of heat in conditioning
Diffusion, swelling, and moisture behavior
Why a rinse conditioner is needed - and why a deep conditioner is beneficial

This series is focused on understanding kinky hair from a fiber science perspective, not just trends. If you're building a healthy hair routine based on structure, elasticity, and long-term strength, this channel is for you.

Subscribe for the full Conditioner Series, where we'll continue discussing:
Deep conditioning with heat, leave-in conditioners, bond builders, protein treatments, and how to optimize your wash day scientifically.
