In 1959, a group of Californians got tired of seeing harsh chemicals in the products they were using manufactured by big companies. They decided to focus on making body loving products with plant based ingredients and using the restorative power of nature's botanicals. Jason which is the Greek word for heale was deemed the name of the company. They then set a code of honor to include 1) Safe, gentle and effective ingredients, 2) Never testing on animals and 3) innovating and improving constantly. You won't find parabens, phthalates, harsh sulfates or artificial colors in their skin, body and haircare products.
Salicylic acid targets clogged pores, promotes the shedding of dead skin cells, and improves the health of the skin, including the scalp [1]. Rosemary oil targets a substance that is associated with hair loss known as dihydrotestosterone (DHT) [2]. Jojoba oil helps loosen and promote the removal of sebum from the scalp, which is a thick substance that is linked to hair loss in some individuals [3]. Olive Oil is a rich source of monounsaturated fats (about 73%), followed by saturated fat (about 14%), and polyunsaturated fat (11%) [4-7]. Monounsaturated fats in olive oil enhance overall health [4-7]. Olive oil contains vitamins E, K, and an ample amount of antioxidants; it improves the body's utilization of vitamins A, D and K as well [8, 9]. All of these vitamins and nutrients help nourish the skin and hair. It also has anti-inflammatory properties that can help improve the health of the skin, including the scalp [10, 11].

Salicylic acid has comedolytic properties that make it a helpful peeling agent that targets photodamage that can damage the scalp and hair follicles [1]. A hormonal imbalance may cause certain enzymes such as 5-alpha-reductase may begin to convert testosterone in both men and women into a stronger substance called dihydrotestosterone (DHT). Increased DHT levels leads to the accumulation of a thick, dandruff-like substance called sebum. Sebum can clog the roots of the scalp, which can subsequently disrupt nutrient transport to the scalp and hair follicles, hair loss. Rosemary oil blocks DHT activity, thereby preventing the buildup of sebum and hair loss [2]. Jojoba oil mimics the texture of sebum and this reduces the production of sebum on the scalp [3].
Olive oil contains a small percentage of polyunsaturated fat (e.g., omega-6 and omega-3 fatty acids) as well as a large percentage of monounsaturated fat called oleic acid, which helps target inflammation, improves heart health and may also have anti-cancer properties [4-7]. The body cannot produce these types of essential acids on its own. Olive oil contains vitamins and antioxidants that improve the body's ability to ward off illnesses [8, 9]. These nutrients help boost the health of the skin and hair. Olive oil contains anti-inflammatory components such as oleocanthal, which help improve the appearance of the skin and can also help target an irritated scalp [10, 11].
