External: • May help hair growth and tissue development. • Garlic oil can be used against eyebrow hair loss. A small amount of oil can be applied to the eyebrows regularly using a cotton swab. • Can be added to shampoos at a ratio of ¼ to strengthen hair strands. What is oil? Oils are organic substances containing high amounts of carbon and hydrogen that do not mix with water but easily mix with other oils. Volatility and Stability in Oils: Fixed Oil • Liquid products obtained from plants, usually fruits and seeds. • Odorless. Used as a carrier in essential oils. Obtained by pressing, extraction, and maceration methods. Fixed oils are used alone. Oils are used internally and externally depending on their properties. Because they are fixed oils, they leave stains when dripped. Essential Oil • Essential oil is a natural product obtained from the leaves, fruits, bark, or roots of plants. It is liquid at room temperature, usually colorless or light yellow, volatile, and has a strong odor. • They have their own characteristic odors. They are obtained by water/steam distillation. Essential oils are not used alone. They should be used diluted with fixed oils in specific ratios. Except for exceptions, they are not used internally. Because they are volatile, they do not leave stains when dripped. Methods of Extracting Oils Cold Pressing This is the process of crushing the seed parts of plants rich in fixed oils and extracting the oil using a press. In the cold press method, the beneficial and valuable components in the oil are not lost, so the quality of the produced oil is high. Steam Distillation The process carried out by steam distillation; The process involves placing plants, fresh or dried, in a container with a separate basket, boiling the water below, and passing the steam through the plants. This steam is then cooled to separate the essential oil and the resulting hydrosol (flower water), which retains the beneficial properties of the distilled plant. Maceration is the process of preparing oily mixtures by allowing crushed herbal drugs to sit in a carrier oil for a period of time. It is a method of separating the natural plant components that have passed into the carrier oil.
