In this detailed guide, we’ll explore benefits, ingredients, usage, suitability, and why this mask is loved by users worldwide.
What Is Advanced Clinicals Keratin Sleek + Smooth Hair Mask?
Advanced Clinicals Keratin Sleek + Smooth Hair Mask is a deep-conditioning hair treatment developed in the USA with globally sourced ingredients. It is specially formulated to repair damaged hair strands, restore moisture, and give hair a smoother, straighter appearance.
Unlike regular conditioners, this keratin mask penetrates deep into the hair shaft to strengthen hair proteins and improve manageability. It works well for dry, brittle, frizzy, and chemically treated hair.

Why Keratin Is Essential for Hair Health
Keratin is a natural protein found in hair, skin, and nails. Daily heat styling, pollution, and chemical treatments strip hair of keratin, making it weak and frizzy.
Using Advanced Clinicals Keratin Sleek + Smooth Hair Mask helps replenish lost keratin and rebuild hair strength. This is why it’s often recommended as a keratin hair mask for frizzy hair and damaged strands.
Benefits of Keratin:
- Strengthens hair fibers
- Reduces frizz and flyaways
- Improves smoothness and shine
- Makes hair more manageable
Power-Packed Ingredients That Make a Difference
1. Hydrolyzed Keratin

2. Shea Butter
