Quick Answer
Yes — with a layering order. Apply lightest to heaviest, water-based to oil-based. A typical order: leave-in conditioner → hair-growth serum (e.g., MD Hair™ Follicle Energizer) → heat protectant → styling product. Wait 2-3 minutes between layers for absorption. The MD Hair™ system is designed to layer cleanly with conventional styling products. Federally registered MD® trademark. Made in USA. www.md-factor.com.
