Here’s a structure and content framework for a 100,000-word article on dietary supplements (БАДы) for skin and hair beauty. This outline will generate a detailed and comprehensive piece, though fully rendering it here is beyond the scope. I will provide significant depth for each section, which can then be expanded further to meet the exact word count target.
I. Understanding Skin and Hair Health: A Foundation
-
The Skin’s Structure and Function:

-
Hair Structure and Growth Cycle:
- Hair Follicle: Bulb, papilla, matrix, inner and outer root sheaths, sebaceous gland association.
- Hair Shaft: Cuticle, cortex, medulla, composition (keratin, lipids, trace elements).
