Why Heat Damages Hair and How to Fix It
High temperatures from flat irons, blow dryers, and curling wands weaken hair’s hydrogen bonds, leading to dryness, split ends, and breakage. The cuticle (outer layer) lifts, causing frizz, while the cortex (inner layer) loses moisture and elasticity. Products with bis-aminopropyl diglycol dimaleate (like Olaplex) rebuild broken bonds, while oils and proteins seal the cuticle. For severe damage, pair treatments with a maintenance routine to avoid further stress.
Top 5 Heat Repair Products
| Product | Key Ingredient | Best For |
|---|---|---|
| Olaplex No. 7 Bonding Oil | Bis-aminopropyl diglycol dimaleate | Severe breakage |
| Kérastase Resistance Serum | Ceramides, vitamin E | Dry, brittle hair |
| Moroccanoil Treatment | Argan oil, linseed extract | Frizz control |
How to Use Heat Repair Products Effectively
Apply treatments to damp hair for deeper absorption. For oils, focus on mid-lengths to ends to avoid greasiness. Use bond builders like Olaplex 1-2x weekly, and always follow with a heat protectant (e.g., Bumble and Bumble Heat Shield). Sleep on a silk pillowcase to reduce friction, and limit heat tools to 350°F or lower. For more on safe heat use, explore infrared safety tips.
