Jojoba is a thick, bushy shrub found in arid and semi-arid regions. It can reach a height of 5 meters. It is a taprooted plant; this main root provides anchorage and stores the plant's reserves. This jojoba root system stabilizes the soil. It also makes the plant resistant to severe drought conditions, to the extent that it can withstand a year and a half without water. The leaves are oval-shaped, leathery, and hairy on both sides. Young leaves are soft green or gray, then turn yellowish-green.
Manufacture of Jojoba Seed Oil
In a screw press, healthy and cleaned fruits are cold-pressed in a first pressing, without the use of any solvents or chemicals. The oil is then filtered successively through blotting paper. The oil is then stored away from light and heat.
Properties of Jojoba Seed Oil
It has numerous properties and benefits for skin and hair.
Properties of Jojoba Oil on the Skin
Stabilizing: it improves the stability of cosmetic products that contain it.
Skin pH regulator: it maintains the skin's acid balance. It increases the excessively low pH of dry skin and decreases the excessively high pH of oily skin.
Sebum regulator: it regulates sebum production. Depending on the skin type, it reduces or increases its production. It therefore improves the appearance of oily or acne-prone skin (excess sebum) and revitalizes dry skin (lack of sebum).
Softening: it restores suppleness and elasticity to the skin. It acts by activating elastin metabolism and slowing down water loss in cells. It thus helps combat skin aging and wrinkles.
Non-occlusive with a comedogenic index of 0, jojoba oil moisturizes the skin without clogging its pores.
Jojoba and Acne: A Winning Duo
Jojoba oil is beneficial for acne-prone skin, as it has regulating, purifying, and soothing properties. Here's how it acts on this skin type:
Regulates sebum production, which is often excessive in acne-prone skin. It rebalances the skin's pH and prevents it from becoming shiny or too oily. This prevents pore obstruction and the formation of blackheads.
Purifies the skin, thanks to its antifungal and antibacterial action. It eliminates impurities, bacteria, and fungi that can cause inflammation, infections, and pimples.
Soothes the skin, thanks to its anti-inflammatory and healing power. It relieves irritation, redness, itching, and feelings of tightness. It promotes the repair of damaged tissues and reduces marks and scars left by acne.
Jojoba oil is therefore an ideal vegetable oil for acne-prone skin, as it nourishes, moisturizes, protects, and beautifies it, without making it greasy or aggressive. It can be used pure or mixed with other vegetable oils, such as black seed oil or tea tree oil, which also have anti-acne properties.

Properties of Jojoba Oil on Hair
Intensely moisturizes hair, thanks to its composition similar to natural sebum. It quickly penetrates the hair, making it soft, shiny, and strong.
Regulates sebum production, depending on hair type. It reduces excess sebum in oily hair and increases sebum production in dry hair. This allows for less frequent shampooing and maintains scalp balance.
Soothes the scalp and eliminates dandruff, thanks to its antifungal and antibacterial properties. It relieves irritation, itching, redness, and inflammation of the scalp. It also cleanses the scalp and prevents dandruff formation.
Protects hair from heating devices, such as hair dryers, straighteners, or curling irons. It acts as a barrier against heat damage. This prevents dehydration and hair breakage.
Deeply nourishes hair, thanks to its richness in vitamins, minerals, and antioxidants. It promotes hair growth, strengthening, and repair. This reduces breakage, split ends, and dry ends.
Beautifies hair and makes it shine, thanks to its light and non-greasy texture. It leaves a smooth film on the hair that reflects light. It also softens hair, making it easier to style and manage.
Properties of Jojoba Oil on Beards
Jojoba oil deeply nourishes beard hair and skin, thanks to its easy penetration into the epidermis and hair follicles. It protects and softens the beard, while making it easier to brush. Its dry feel makes it pleasant to use.
Moreover, jojoba oil can replace shaving foams, which are often irritating and harmful to the skin. Jojoba oil allows for a gentle shave, while protecting the beard from razor aggressions.
Jojoba oil easily replaces any aftershave.
