Our Approach to Thick,
Beautiful Hair

Studies show that as early as your late teens or early 20’s, hair becomes more brittle, and thin. While you might not experience what is traditional “hair loss”, your hair may break easier due to heat and over processing, which causes your hair to look thin and uneven. Damage to your hair makes it much harder to grow. Split ends can make your hair shorter by the day (literally).
Theorem™ is the first hair brand system to devise a 3-dimensional solution to achieve thicker, healthier hair from root to tip.

The hair cycle

The hair cycle includes three phases: growth, regression and quiescence.
These phases are commonly called the anagen, catagen and telogen phases.

The
anagen
phase.

The anagen phase.

This is the phase of active hair growth and lasts from 3 to 5 years. In a normal scalp, 80-85% of the hair follicles are in anagen phase and each follicle can successively yield about 20 terminal hairs.

The
catagen
phase.

The catagen phase.

This is the phase of regression of the hair follicle that lasts about 3 weeks. The cells become keratinized, mitotic activity stops, the follicle no longer manufactures hair and takes the form of a club.

The
telogen
phase.

The telogen phase.

This is the quiescent phase that lasts about 3 months. During this period, the hair is anchored in the follicle and continues to rise. At the end of this phase, the hair falls and a new cycle starts.
