The Science
"SEEN is a brand steeped in science. Hair care products can cause skin and scalp issues, including acne, eczema, irritation, dry scalp and fragrance sensitivity. I experienced this personally. I found myself having to choose between gorgeous hair and healthy skin, when I wanted both. We decided from the start that when we make a claim, we back it up with science. SEEN is luxury, clean, vegan hair care with skin benefits. The best of hair care and skin care in one."

Why hair care is skin care
What’s on your hair is on your skin
Even rinse-off products can leave a residue that transfers to skin and stays on skin for hours. The deposition on skin from leave-in products increases substantially over time—even up to 4 hours after application. Hair product residue gets on the skin as product rinses down the face and body in the shower, or transfers from hair or a towel/pillowcase to the skin.
Findings
There is an absence (dark blue) of the hair product residue on the skin before applying hair products to the hair. After applying hair products to the hair, a significant amount of product residue gets on—and stays on - the skin (even rinse-off products). Even 2-4 hours after using hair products, residue remains on the skin.

The Science Behind SEEN
We don't use the word "science" lightly. SEEN applies skin science and testing to hair care because hair care products end up on the skin.
Early in the formulation process, Dr. Rubin actually applied versions directly to her face, as an initial test to see if the product will cause breakouts or irritation. All SEEN formulas ultimately go through formal third party testing before they are approved. In addition, we consult with contact allergen specialists to gather input on ingredients and new data about ingredient reactivity.
Once a product formula is approved, that's just the start. The formula then goes through a battery of tests, including:
All final formulations are subjected to 3rd party clinical comedogenicity testing to ensure that they won't clog pores, which can cause breakouts.
We’re proud to announce that our fragrance-free Shampoo, Conditioner, Deeper Conditioner, Blow-Out Creme, Curly Creme and Magic Serum have received the NEA Seal of Acceptance™—which means people with sensitive or eczema-prone skin can enjoy SEEN.
All final formulations are subjected to 3rd party RIPT testing to ensure they are non-irritating, and safety and allergy tested.
All final hair care formulations are subjected to 3rd party testing to ensure they are color-safe.
All final hair care formulations are subjected to 3rd party testing to assess the extent to which they protect the hair against breakage.
All final hair care formulations are subjected to 3rd party testing to assess the extent to which they reduce frizz.
Relevant formulations are subjected to 3rd party testing to assess the extent to which they protect the hair from heat damage from styling tools.
Relevant formulations are subjected to 3rd party testing to assess the extent to which they boost volume.
All final formulations are subjected to 3rd party testing to ensure they are gluten-free and soy-free.

Is natural always skin-friendly?
Just because a product is natural does not make it skin-friendly. Hint: poison ivy is 100% natural. Certain botanicals and essential oils can irritate the skin, cause skin allergies, or clog pores. SEEN's formulas include the best of both natural and safe synthetic ingredients to give you the best hair and skin benefits.
