Ceramides (NP, AP, EOP)

What are ceramides?

Ceramides are a class of lipids (fats) naturally present in everyone's skin. They make up about 50% of the epidermal lipid barrier — that thin layer that protects the skin from water loss and from harmful substances entering from outside. You could say ceramides are like the mortar between bricks: the bricks are dead epidermal cells (corneocytes), and ceramides are the lipid mortar that binds them into a tight, functional barrier.

At Trichovita we use three specific types of ceramides: Ceramide NP, Ceramide AP, and Ceramide EOP. These are structurally identical counterparts to the ceramides that naturally occur in the skin, only obtained through a biotechnological process (from yeast or fermentation), which makes them fully vegan and ethically neutral. Under a microscope, after application to the skin, they are indistinguishable from those the skin produces itself.

This is an important distinction: many cosmetic brands use "plant ceramides" (mainly from rice or wheat oil) — these are phytoceramides, which are only analogs. Our ceramides are real ceramides, identical to human ones.

How do ceramides work on the scalp and hair?

A lipid barrier problem is rarely the first thing we think of when dealing with hair loss — and yet it's fundamental. When the scalp's barrier is weakened (due to frequent washing with aggressive shampoos, heat styling, stress, hormonal changes, dryness), the skin loses water faster than it replenishes it, becomes hyperreactive, and vulnerable to irritation. In this state, hair follicles function worse — they are surrounded by tissue in chronic stress rather than healthy tissue.

Ceramides act directly on this problem. When applied to the scalp in liposomal form, they integrate with the existing lipid layer of the epidermis and fill the "gaps" in its structure. The effect is measurable: transepidermal water loss (TEWL) drops, the skin regenerates faster, and reactions to irritants (shampoo, styling, weather changes) are less dramatic.

In the context of hair, the effect is indirect but important: a well-hydrated, functional scalp is a better environment for the hair follicle. Bulbs are not in an inflammatory stress state, are better supplied with blood, and follicles more easily keep hair in the growth phase. Ceramides are not an "anti-hair-loss ingredient" in the marketing sense — they are an ingredient that creates the conditions in which hair grows better.

Why do we use ceramides in Trichovita?

Most trichological cosmetics skip ceramides. Why? Because they're expensive — real biotechnological ceramides cost many times more than cheaper alternatives like plant oils or "wheat ceramides". In a regular water-based formula, ceramides are also hard to use because they're water-insoluble and tend to precipitate in unstable emulsions.

We have two reasons for using them despite the cost: first: effectiveness. There is no substitute for structurally identical ceramides when it comes to rebuilding the scalp barrier. Second: synergy with liposomal formulation. Liposomes are built from lipids, so ceramides are naturally compatible with the delivery method in our formula. In a regular water-based formula, ceramides would be a problem — in liposomes, they are ideal.

Which Trichovita products contain ceramides?

Ceramides are present in our serum (not in the mask). The decision is deliberate: ceramides work best with daily, systematic application to the scalp, and the serum is designed exactly for this. The mask has a different role: intensive conditioning of hair and scalp using plant oils and other lipids (shea butter, hemp oil). These two formulas are complementary: the serum takes care of the barrier, the mask regenerates more invasively.

Are ceramides right for you?

Ceramides in the serum are especially worth considering if:

• Your scalp is dry, tight, or itchy — these are classic symptoms of a weakened lipid barrier, and ceramides directly address it.
• You often use aggressive shampoos, heat styling, or hair dye — all these factors damage the scalp's barrier, and ceramides are needed for its regeneration.
• You're prone to dandruff, seborrheic dermatitis, or other scalp problems — a weakened barrier is often a contributor, and rebuilding it eases symptoms.
• You live in a climate with low air humidity (air conditioning, winter heating) — these conditions dry out the skin, and ceramides help maintain hydration balance.
• You're post-menopausal or peri-menopausal — the level of natural ceramides in the skin drops with age, and especially after menopause; supplying them externally is logical.
