Collagen is one of the most important proteins in our bodies. It supports your bones, organs, teeth, tendons, and skin. One of its most important properties is its impact on hair regeneration and growth. High collagen counts lead to healthier, fuller hair.

How fragile your hair depends on your levels of keratin. Those with higher levels of keratin are more likely to have tough, resilient hair, while those with lower levels tend to have hair that is more likely to break or shed.

Dry hair results when the outer layer of your hair breaks down, losing its shine. Apart from looking dry, it’s also more prone to shedding or breakage. While proper hair care and maintenance can help you keep your hair from drying out, it is important to note the various genetic factors that can lead to dry hair.

How fast your hair grows is largely based on your genetics. While there are some things you can do to stimulate hair growth, such as keeping it healthy, the main thing that determines how fast your hair grows is your DNA.

Your hair is protected by a hydro-lipid layer, which maintains the flexibility of your hair and keeps it well hydrated. Keeping your lipids balanced is the key to making sure your hair is healthy and hydrated.

Your hair starts to grey when one of two things happen: either pigment production in your hair is slowed, or you build up too much hydrogen peroxide. Both of these are associated with aging, but can also be caused by stress or vitamin deficiencies.

The thickness of your hair is based on the thickness of each individual strand. When each hair is larger, your hair appears fuller and healthier. Your hair’s thickness is based on the amount of collagen surrounding it, which can often be stripped down from overwashing.

Keeping your scalp’s levels of antioxidants balanced is a major factor in maintaining smooth, healthy skin and hair. An imbalance of antioxidants not only affects the skin by causing premature aging but can lead to many chronic and late-onset diseases that affect your body as a whole.

Your scalp is one of the most important parts of your skin. It serves as a barrier, blocking toxins and allergens from entering your skin and damaging your hair. It also serves in maintaining proper skin hydration. Those with damaged or weakened scalps are far more likely to suffer from allergies or sensitivities than those with healthy scalps.

Your scalp is constantly shedding a skin - it’s perfectly natural. However, when such shedding happens more than usual, it can be the result of a hormonal imbalance or other problems with your skin. Excessive scalp flaking can lead to patches, red or irritated skin, and dandruff.

Glycation occurs when the body doesn’t process glucose correctly and causes damage to your skin. It often leads to irritation, and can even damage your hair if not addressed correctly. Glycation is often caused by having too many sugary foods, which are high in glucose.

In order to keep your scalp healthy, making sure you’re staying hydrated is absolutely essential. However, keeping your scalp hydrated is harder for some than others. The strength of your aquaporin channels - proteins that allow water to travel between your skin cells - is determined by your genetics, meaning they work better for some than for others.

Scalp irritability, also called inflammation, is a biological response to allergens or toxins. A number of things can lead to inflammations, ranging from sun exposure, stress, toxins (e.g. pollution, smoking, trauma, alcohol, immune reactions, infections, etc.), pathogens, and foreign bodies (such as dirt and debris).

Your scalp’s capacity for pollution defense determines how your body reacts to pollution, typically that from the air. Repeated contact with high volumes of air pollution can cause dull hair, inflammation, and faster aging.

Your scalp is still at risk of being damaged by the sun, even though it’s typically covered in hair. Taking steps to protect it from sun damage can reduce your risk of having your hair or scalp damaged by the sun’s radiation.

Though your scalp is typically home to the thickest skin on your body, it can become thinner and more fragile as you age. A key factor in this process is your genetics, which determines just how fast your skin gets thinner.

Sebum is an oily, waxy substance that your body produces to trap moisture in and keep your skin hydrated. Sebum overproduction results in oily skin or scalp and is a major factor in ‘greasy’ hair. Keeping your sebum production balanced helps you have healthy, clean skin and hair.
