Buying Notes
Match mask protein level to hair porosity and history: low-porosity/fine hair — choose lighter, balanced formulas; high-porosity/damaged hair — choose fuller protein/keratin blends. Start with a 5–15 minute leave-in test window before trying longer treatments. Rotate a protein-containing mask with a moisturizing mask to avoid stiffness. Always follow with gentle detangling and minimal heat.

Frequently Asked Questions
How often should I use a strengthening deep mask?
1–2 times per week for most thinning hair. If hair feels stiff, reduce frequency or shorten leave time.
Can a mask cause protein overload?
Yes. Signs are stiffness, increased breakage, or dullness. Switch to moisturizing masks and reduce protein treatments.
Which mask is best for fine, thinning hair?
Choose lighter, balanced formulations — look for 'biotin' or gentle protein blends and short leave times.
Can I use these masks on colored or chemically treated hair?
Yes — most are safe for colored hair. Pick a formula that matches damage level: more porous/bleached hair typically benefits from moderate protein.
