What is hemp seed oil?
Hemp oil is a vegetable oil cold-pressed from the seeds of industrial hemp (Cannabis sativa). One thing needs to be emphasized: these are seeds, not flowers. Hemp flowers contain cannabinoids (THC, CBD) and are legally regulated in many countries. Seeds are entirely safe, legal everywhere, and have been used for centuries as food and a cosmetic raw material.
The chemical composition of hemp oil is exceptionally valuable for the skin: it contains an ideal ratio of Omega-3, Omega-6, and Omega-9 fatty acids — exactly in the proportion in which the skin needs them for optimal functioning. In addition to this, hemp oil contains phytosterols, carotenoids (vitamin A), vitamin E, and other lipophilic components supporting skin regeneration.
Hemp oil also has one very characteristic feature: it's lightweight. Unlike heavy oils like coconut oil or castor oil, which can weigh down hair and scalp, hemp oil absorbs relatively quickly and doesn't leave a greasy coating. This makes it ideal for use on scalp and hair, even in people with a tendency to oily seborrhea.
How does hemp oil work on the scalp and hair?
The fatty acids in hemp oil have several important functions in the context of the scalp. The most important is strengthening the epidermal lipid barrier. The skin's barrier, simply put, is a mixture of lipids produced by epidermal cells. When this barrier is weakened (by stress, aggressive washing, excessive flaking), the skin loses water and becomes sensitive. Lipids from hemp oil — especially linoleic acid (Omega-6) and gamma-linolenic acid (GLA) — are structurally similar to skin lipids and integrate with the natural barrier, partially supplementing it.
Omega-3 and Omega-6 acids also have documented anti-inflammatory action. They inhibit the synthesis of pro-inflammatory prostaglandins in the skin, which translates to less redness, less itching, less reactivity to irritants. In the context of the hair follicle, this means better conditions for the bulb. Inflammation around the follicle is one of the factors accelerating follicle miniaturization and hair transition into the telogen phase.
Phytosterols in hemp oil have a very specific action: they regulate the activity of the enzyme 5-alpha-reductase, which in the scalp converts testosterone into dihydrotestosterone (DHT) — the main culprit of androgenetic alopecia. This is not a cure for androgenetic alopecia (that requires pharmaceuticals like finasteride), but it can be gentle, natural support in prevention.
Carotenoids and vitamin E in the oil have antioxidant action — they protect scalp cells from damage caused by free radicals (pollution, UV radiation, metabolic stress).
Why do we use hemp oil in Trichovita?
When we were designing the mask, we were looking for a plant oil that would be effective, lightweight, and safe for all scalp types. We had several candidates — avocado oil, black cumin oil, almond oil — and all have their merits, but hemp oil won for specific reasons.
First, an ideal fatty acid profile. Most plant oils are dominated by one type of acid (e.g., olive oil is mainly Omega-9). Hemp oil has an exceptionally balanced mix of Omega-3, Omega-6, and Omega-9 in proportions close to what the skin actually needs.
Second, low comedogenicity. Comedogenicity is the tendency of an ingredient to clog pores. Hemp oil has a very low comedogenicity rating — it doesn't clog hair follicles, which is key in a product applied to the scalp. Heavy oils (castor, coconut) are comedogenic and can worsen seborrhea problems.
Third, no dominating fragrance. Hemp oil has a delicate, herbal scent that blends well with other mask ingredients without being overpowering.
Which Trichovita products contain hemp oil?
Hemp oil is present exclusively in the mask (not in the serum). This decision stems from two things: first, plant oils work best with intensive, short-term application (like a 15-minute mask), not with a daily leave-in serum. Second, the mask is a natural "oil application" — users expect a rich, oily texture in a mask, and a lightweight, fast-absorbing texture in a serum.
Is hemp oil right for you?
This ingredient is especially worth considering if:
- You have a dry, sensitive, or irritated scalp — lipids in hemp oil directly strengthen the barrier, which calms the skin.
- You have a tendency to scalp itching or redness — the anti-inflammatory action of Omega-6 helps reduce reactivity.
- Your hair is dry, brittle, or weakened — fatty acids provide the scalp with substances needed to produce healthy hair.
- You have early-stage androgenetic hair loss — the gentle action of phytosterols on 5-alpha-reductase can be a valuable support (alongside professional diagnosis).
- You're sensitive to strong cosmetic fragrances — hemp oil has a natural, mild scent and doesn't need masking with synthetic fragrances.
Frequently asked questions
Does hemp oil contain THC or CBD?
No. The hemp oil used in cosmetics (and by us) is cold-pressed from the seeds of industrial hemp (*Cannabis sativa*), not from flowers or leaves. Seeds contain only trace amounts of cannabinoids, practically zero THC and CBD. This is a regular edible/cosmetic oil, in the same category as avocado oil or olive oil.
Won't hemp oil weigh down my hair?
No, because the mask is rinsed off. Hemp oil in the mask works for 15 minutes directly on the scalp and hair, and then is washed out. In this short window, lipids penetrate the cuticle (forming a film on the outside of the hair) and the scalp (rebuilding the barrier). What remains after rinsing is the regenerative effect — not a greasy residue. That's why the mask has such specific usage instructions.
Can I use hemp oil if I have oily hair?
Yes, especially if you have oily hair. The paradox: hair is often oily due to excessive sebum secretion by the scalp in response to dryness. Hemp oil helps regulate sebaceous gland activity and strengthens the natural lipid barrier, which indirectly reduces sebum overproduction. After several weeks of mask use, many people notice that their hair stays fresh longer.
Where does our hemp oil come from?
From certified European producers who use cold pressing (without high temperatures that destroy sensitive fatty acids). Cold pressing is more expensive but preserves the full biological value of the oil — it's the same raw material used by top spa cosmetics. The oil comes from organic farms, pesticide-free.
