Skin Actives Double Action Hair Serum was formulated by a female scientist to help with hair thinning and graying. Its key ingredients Keratinocyte Growth Factor (KGF), Methionine Sulfoxide Reductase (MSR), and nourishing actives work to create thicker, stronger, and healthier looking hair while helping preserve hair’s natural color.
A key ingredient is the Keratinocyte Growth Factor (KGF) (INCI: sh-Polypeptide-3). The antioxidative naturally produced substance is meant to boost the production of new hair cells and can be used to increase the efficacy of existing formulas. Hair formulations with this ingredient are used on thinning or damaged areas. Although dead hair follicles cannot reactivate, the ingredient reportedly can aid unhealthy follicles. One customer review suggests the serum also has the potential to boost hair regrowth for someone post-chemotherapy.
Skin Actives has also developed a series of antioxidative, bio-identical proteins, which are meant to supplement the body's defenses against oxidative stress that contributes to the effects of aging. These proteins include:
- Glutaredoxin (INCI: sh-Polypeptide-77 (and) Oxido Reductase), an enzyme that protects against oxidative stress;
- Thioredoxin (INCI: sh-Polypeptide-2 (and) Oxido Reductase), a protein found in nearly all known organisms that acts as an antioxidant by facilitating the reduction of other proteins.
- Superoxide Dismutase (SOD) (INCI: Superoxide Dismutase) works to eliminate free radicals and prevent chain reactions that can reach deep into the skin.
These proteins and KGF were used to create a product line that protects skin and hair from the effects of pollution. One such product is the brand's Double Action Hair Serum, which is meant to help create thicker, stronger hair with fewer grays.
There are a few options for optimal use; one is to use nightly by applying directly to the scalp area using the product's pointed applicator. Gently massage onto a damp scalp nightly then rinse or cleanse in the morning. Another option is to add to wet hair in the morning and style. Due to its oil base, using a small amount will add volume, body, and shine. The manufacturer suggests consistent use for two to six months for best results.
