Essential Oil Alternatives: DIY Shampoo

Finding a good shampoo is akin to spotting the perfect outfit. Whether you’re seeking deeply conditioned locks or silky smooth tresses, there are aisles of products to suit your needs. The problem with over-the-counter hair care products is that many are adulterated with toxic ingredients that can have long-term harmful effects.


The skin is the largest organ on our bodies and it easily absorbs nearly everything slathered on it. On average, the skin absorbs 64% of what we put on it according to a study published in the American Journal of Public Health. Beyond that, chemicals are more likely to penetrate the face and scalp.

Formaldehyde is one of the most toxic chemicals often included in beauty and personal care products. A report by the Federal Drug Administration found that nearly 1 in 5 cosmetic products contain a substance that generates formaldehyde, a known human carcinogen. The sad truth is product labels are unlikely to reveal formaldehyde as an active ingredient. Instead, the ingredient list might include chemicals that are known to be a formaldehyde releasers such as DMDM hydantoin. Used as a preservative, DMDM hydantoin can cause irritation to the eyes, skin and lungs.

Another preservative, methylisothiazolinone, is a known human immune toxicant or allergen according to the European SCCS. Beware of shampoos and conditioners that claim to be “natural.” The FTC has found numerous cosmetics with synthetic ingredients that were labeled as “all natural” or “100% natural.” As a general rule, if you can’t identify the ingredient list, it’s best to avoid the product. Retinyl Palmitate (or vitamin A palmitate) is a skin-conditioning agent that is banned in Germany and restricted in Canada. According to a study by the FDA, the chemical may speed the development of skin tumors and lesions.

As noted in EG’s other Go Clean in 2017 posts, fragrance is extremely harmful to our health. Although we may love the way a certain shampoo scents our hair, it may come at a high cost. Beyond disrupting the endocrine system, fragrance is a possible human respiratory toxicant. Instead of using synthetic fragrances, essential oils act as a natural alternative for all of your aroma needs.


EG’s undiluted and 100% pure essential oils are packed with components that can refresh and nourish your hair. Rosemary naturally stimulates the hair follicles, making your strands stronger, while it helps eliminate dandruff. Peppermint can help restore the scalp’s natural pH balance and promote healthier hair.

    Hi Erica! We recommend checking with a cosmetic ingredient supplier when choosing the right preservative for a product.

    What kind of preservative should be added to extend shelf life?

  • Edens Garden says...

    Hi Jasmine! This recipe has a shelf life of a week to two weeks without a preservative. If you wish to extend the shelf life, we recommend adding a preservative.

  • Jasmine says...

    Looking forward to making this! Do I need to add a preservative? If no preservatives are needed, what is the shelf life for this?

  • Edens Garden says...

    Hi Gabby! The total number of drop is 18, or less if you prefer. Some other hair nourishing essential oils include Geranium, Grapefruit, Lemon, Neroli, Sandalwood and Cedarwood.
