Caldera + Lab - The Hair Serum

Hero Ingredients: A high-performance complex for scalp and hair health.

ExoDense™ Complex: The engine of the formula. This complex features Plant Exosomes, which are like tiny delivery vehicles from plants that carry bioactive nutrients directly to your scalp. It also includes Caffeine to stimulate the scalp and adaptogenic botanicals to help balance its microbiome.

Biomimetic Peptides: These are smart proteins that help to reinforce the structure of the hair shaft itself. This makes the hair stronger, more resilient, and less prone to thinning and breakage.

Amino Acids: These are the essential building blocks of protein. They help to fortify the hair fibers and provide foundational nourishment for the scalp.

Plant Stem Cells: Sourced from apples, these help to support the skin's natural regeneration process on the scalp and protect it from daily environmental stress.

Balances the Scalp Microbiome: Creates an optimal, healthy environment for your hair follicles to thrive.

Fast-Absorbing and Non-Greasy: The lightweight formula absorbs quickly without leaving any sticky or oily residue.

Apply daily to a dry or damp scalp.

Step 1: Apply 1-2 full pipettes of the serum directly to your scalp. Part your hair as needed to ensure the dropper tip reaches the skin.

Step 2: Gently massage the serum into your scalp with your fingertips to ensure even distribution.

Step 3: Leave the serum in. Do not rinse it out. Style your hair as usual.

This product is dermatologist-tested and fragrance-free. However, it contains a highly concentrated blend of numerous botanical extracts.

The 2nd's Recommendation: For external use only. If you have a very sensitive scalp, a patch test is always a good idea

Treating your scalp with the same care you give your face is a major step toward better hair health. This serum makes that step easy. Because it's a lightweight, non-greasy liquid, it's perfect for applying directly to the scalp without making your hair feel heavy or styled. Remember that with any product targeting hair growth cycles, patience and consistency are the most important factors for seeing results.

This product is fragrance-free.

How does this serum actually work?
It takes a multi-pronged approach. First, it focuses on creating a healthy, balanced scalp by supporting its microbiome. Second, it delivers stimulating and nourishing ingredients like caffeine and plant exosomes directly to the hair follicles. Third, it strengthens the existing hair strands with peptides and proteins to reduce breakage, which helps you retain more hair for a fuller look.

Will this make my hair greasy?
No. It's a very lightweight, water-based serum, not an oil. It's designed to absorb quickly into the scalp itself, leaving no sticky or greasy residue on your hair.

How long until I see results?
While your hair may feel stronger sooner, the benefits to hair growth cycles take time. With consistent daily use, clinical studies show visible improvements in thickness and a reduction in hair fall after 12 weeks.
