Hair Type: Fine, Medium, and Thick
Hair Texture: Straight, Wavy, Curly, and Coily
Hair Concerns:
- Damage/Split Ends/Breakage
- Dryness
- Shine
Key Benefits:
- Stimulates and Soothes Itchy Scalp
- Provides Essential Nutrition to Support Healthy Hair Lengths
- Seals Cuticle from Root to Tip to Recover Damaged Hair
Highlighted Ingredients:
- Creatine R: A blend of amino acids that strengthen the internal structure of hair strands.
- Ceramides: Aid in strengthening hair, enhancing shine, promoting elasticity, and adding moisture.
What Else You Need to Know: Hair lengths, also known as the mid-section between the root and tip of each hair strand, are key contributors to healthy hair. Strong lengths help fortify ends to prevent splitting and breakage for visibly longer hair. This energizing leave-in hair serum stimulates the scalp and reinforces hair at the root to reduce the appearance of split ends. Its soothing, nutrient-rich formula is recommended by professional stylists for renewing the scalp and hair and improving overall hair health.
