Oil Dissolves Grease and Cleanses Hair Follicles
One might think that applying oil to the scalp will clog hair follicles. However, the core principle of oil shampooing is using oil to dissolve grease, Tseng said. Years of accumulated sebum and dirt in the scalp’s hair follicles are often difficult for ordinary shampoos to remove completely. High-quality cold-pressed plant oils penetrate and dissolve these wastes, allowing the hair follicles to breathe again.
Plant and Essential Oils for Shampooing
Tseng suggests the following plant and essential oils for an oil shampoo:
Plant Oils
There are several base oils to choose from:
- Cold-pressed extra virgin olive oil
- Cold-pressed extra virgin coconut oil
- Cold-pressed extra virgin sesame oil
Cold-pressed extra-virgin sesame oil has a milder scent, whereas cooking sesame oil is roasted and has a stronger aroma, making it less suitable for skincare and haircare.
Essential Oils for Oil Shampoo
By using just a few drops of essential oils, you can tailor the blend to address specific scalp concerns:
- Rosemary: Promotes blood circulation and hair growth
- Atlantic Cedarwood: Balances oil secretion and helps prevent hair loss
- Tea Tree: Provides antibacterial support, controls oil, and reduces dandruff
- True Lavender: Soothes redness, reduces swelling, and supports sensitive scalps
- Peppermint: Cools the scalp, controls excess oil, and relieves itching, especially during summer
Research has shown that rosemary and cedarwood essential oils promote hair growth in animal models, with effects comparable to the hair growth agent minoxidil.
How to Wash Hair With Oil
Tseng washes her hair with oil as follows:
- Prepare Massage Oil: Use 0.5 to 1 ounce of plant oil, adjusted based on hair length. The essential oil concentration is typically around 1 percent, equivalent to about two drops of essential oil per 0.5 ounce of plant oil.
- Apply the Oil: After sectioning the hair, apply the oil to the scalp with your fingertips. Focus on the scalp when washing your hair, ensuring it is completely covered with oil, or use a pointed bottle to squeeze the oil directly onto the scalp.
- Massage the Scalp: Insert your fingers deep into your hair and massage your scalp with your fingertips. You can also use a scalp massage comb.
- Condition the Hair: Apply any remaining oil to your hair as a conditioner.
- Let It Sit: Leave the oil on your scalp for 30 minutes if time allows.
- Wash It Out: Shampoo your hair one to two more times than usual to thoroughly cleanse the scalp of excess oil.
Oil Bath Dissolves Toxins
In addition to scalp care, Tseng also recommends a “deep detox oil bath.” In winter or when you are feeling stressed, apply a thick layer of plant oil to your entire body, including areas with high lymphatic density, such as the armpits, inner thighs, and chest. “On these areas of the body that we don’t usually touch and where blockage is especially severe, the oil scraped off is particularly dark!”
Recommended Essential Oils for Baths
Tseng recommends three essential oils suitable for all skin types to relax your mind and body while caring for your skin:
- True Lavender: Promotes relaxation and balances oil secretion.
- Frankincense: Supports antiaging, skin repair, anti-inflammatory effects, and immune function. Some studies have found that frankincense essential oil has anticancer properties.
- Rose Geranium: Balances hormones and keeps skin moisturized. Clinical studies have found that the aroma of geranium essential oil can reduce pain, anxiety, and stress.
How to Prepare and Take an Oil Bath
Tseng suggests the following steps:
- Prepare the Oil: Prepare 1 to 3 ounces of massage oil. The essential oil concentration is usually around 1 percent, or about 20 drops of essential oil per 3 ounces of plant oil.
- Apply the Oil: Apply the oil over your entire body, including your face, ears, navel, nail crevices, soles of your feet, and scalp—if desired.
- Massage the Body: Massage yourself after applying the oil, then put on a bathrobe to keep warm and wait 20 minutes.
- Remove Excess Oil: Wipe off excess oil with a cloth or paper towels before entering the bath to prevent it from pouring down the drain. Oil solidifies when it contacts cold air, which can cause drain blockages. You can also pour a little baking soda into the drain to help prevent sticking.
- Wash It Off: Rinse the oil thoroughly with soap or shower gel after soaking in the bath.
Tseng emphasizes the importance of avoiding slips when using oil for a bath. Wear nonslip bathroom slippers, sit on a chair while showering, and thoroughly scrub the floor and slippers with baking soda and dish soap afterward to help prevent falls.
Precautions
Although oil washing and bathing are relaxing, they are not recommended for people with wounds, inflammation, or redness on the skin or scalp.
