This has been doing wonders for my super fine, slow to grow hair....Love the product but have to take away a star because the applicator barely picks up any product....Apart from that frustration, I've noticed my hair is fuller looking and stronger, so I've got no complaints about the actual serum....This product has done wonders for my hair, but like everyone else has said, the dropper it comes with is terrible!
What it is:
A powerful, antiaging overnight treatment serum that helps maintain strong, healthy hair and follicles.

What it is formulated to do:
Much like skincare for the scalp, this intensive, overnight, non-greasy serum uses advanced technology based on stem cell technology, copper peptides to nourish, and ingredients that normalize and stabilize thinning hair and support scalp health. Not only does it remove debris, sebum, and build-up from the scalp, but it contains a DHT-inhibitor to unclog follicles and promote effective penetration of other treatments.

It provides the scalp and hair follicle with polyphenols, zinc, and glycine to encourage revitalization of the hair growth cycle, helping support a healthy scalp, which encourages hair growth. It contains the proprietary keratin amino complex, which was developed to act on and effectively address all three fundamental parameters of hair strength: tensile properties, torsional stretching, and cuticle abrasion. It penetrates into the cortex of hair, building strength from within, and reinforcing and protecting hair's surface. It’s enriched with an immediate filament protein, which contributes to hair's core strength—sustaining the hair's integrity as it grows from root to tip, and throughout the growth process.

What it is formulated WITHOUT:
- Parabens
- Sulfates
- Phthalates

What else you need to know:
This product can be used every night or every other night. The non-greasy formula does not require you to wash your hair in the morning. The Keranique system of haircare solutions was developed to effectively cleanse, protect, treat, and repair both thin or thinning hair and the scalp. Mild cleansers, clean conditioners, intensive treatments, and lightweight styling products deliver healthy, natural hair growth, abate hair loss, maximize fullness, and care for the scalp—creating an optimized environment to promote the enduring strength, growth, and beauty of hair.
