Hair Growth with Essential OIls


We know that many shampoos actually contribute to hair loss. We discuss this at the end of the post. So be sure to stick around if you aren't sure what to look out for when buying your shampoo. Right now, let's talk about hair growth and essential oils.


The Science of Essential Oils for Hair Growth Before, During, and After Chemotherapy


Hair loss is a common and often distressing side effect of chemotherapy. While there is no guaranteed solution, emerging research suggests that essential oils may play a role in promoting hair growth and scalp health. Let's explore the science behind essential oils and their potential to help restore hair before, during, and after chemotherapy.


Understanding Hair Growth and the Role of Essential Oils


Hair growth follows a cyclical process involving three main phases:


  • Anagen (growth phase)
  • Catagen (transition phase)
  • Telogen (resting phase)


The key to supporting hair growth lies in stimulating the dermal papilla, which regulates follicle function. Recent studies have begun evaluating essential oils for their potential to influence these phases positively. Essential oils are highly concentrated plant extracts obtained through pressing or steaming, and their therapeutic properties have been recognized for centuries.


Essential Oils for Hair Growth


1. Lavender Essential Oil

Lavender oil has been found to promote cell growth and reduce stress, both of which are beneficial for hair regrowth. A 2015 NIH-funded study demonstrated that lavender oil stimulated hair growth in mice, suggesting its potential effectiveness in humans (Gee Young et al., 2015).


2. Peppermint Essential Oil

Peppermint oil is known for its tingling sensation, which increases circulation to the scalp. A study published in Toxicological Research (2014) found that peppermint oil significantly increased follicle number and depth in mice after four weeks of topical application (Park & Kim, 2014).


3. Rosemary Essential Oil

Rosemary oil has been shown to be as effective as minoxidil (a common hair growth treatment) but with fewer side effects. A 2015 study published in Skinmed found that rosemary oil improved hair regrowth in individuals with androgenetic alopecia (Panahi et al., 2015).


4. Cedarwood Essential Oil

Cedarwood oil balances scalp oil production and has antifungal properties that help prevent dandruff-related hair loss. A 1998 study in Archives of Dermatology found that cedarwood, when combined with other essential oils, improved hair regrowth in 44% of participants with alopecia areata (Hay et al., 1998).


5. Lemongrass Essential Oil

A study in 2015 found that lemongrass essential oil significantly reduced dandruff when applied daily for one week, making it a great addition to scalp treatments (Chaisripipat & Rattanachaikunsopon, 2015).


6. Thyme Essential Oil

Thyme oil stimulates the scalp and has been found to be beneficial in treating alopecia areata. It is often used in combination with other essential oils to promote hair regrowth.


7. Clary Sage Essential Oil

Containing similar compounds to lavender oil, clary sage can improve hair strength, reduce breakage, and enhance growth. Mixing three drops into a conditioner can support hair health.


8. Geranium Essential Oil

A 2017 study published in BMC Complementary and Alternative Medicine demonstrated that geranium extract (GSE) stimulated dermal papilla cells and promoted significant hair growth in mice (Boisvert et al., 2017).


9. Tea Tree Essential Oil

Tea tree oil has antimicrobial and anti-inflammatory properties that can help keep the scalp healthy, reducing hair loss caused by infections and buildup.


10. Jojoba Oil

While not technically an essential oil, jojoba oil has been shown to support hair growth. A 2010 study found that a 1% jojoba oil solution improved hair regrowth in mice more than a carrier oil alone (Healthline, 2010).


How to Use Essential Oils for Hair Growth


To incorporate essential oils into your hair care routine, follow these tips:


  • Scalp Massage: Mix a few drops of essential oil with a carrier oil (e.g., coconut, jojoba, or argan oil) and massage into the scalp.
  • Add to Shampoo/Conditioner: Add 2-3 drops of essential oil to your sulfate-free shampoo or conditioner.
  • Overnight Treatment: Apply a diluted essential oil blend before bed and rinse in the morning for deeper penetration.


Final Thoughts about Essential Oils


While essential oils are a promising natural remedy for hair loss, they are not a one-size-fits-all solution. If you are undergoing chemotherapy or experiencing hair loss, consult a healthcare provider before trying essential oils to ensure they are safe for your condition. Consistent use and proper application may help nourish the scalp and support hair regrowth over time. Now let's talk about chemicals to avoid and how to choose the right shampoo.



Choosing the Right Shampoo


When looking to improve hair health, it’s essential to not only focus on what you’re adding—like essential oils—but also what you’re avoiding. Many commercial shampoos contain harsh chemicals that can strip the scalp of its natural oils, leading to dryness, irritation, and even hair loss. Here are some common chemicals to watch out for and why they should be avoided:


1. Sulfates (Sodium Lauryl Sulfate & Sodium Laureth Sulfate)


  • These are detergents that create lather, but they can be extremely harsh on the scalp, stripping away natural oils and causing dryness or irritation.
  • Sulfates have been linked to increased hair breakage, especially for people with curly or color-treated hair.


2. Parabens (Methylparaben, Propylparaben, Butylparaben, Ethylparaben)


  • These preservatives extend the shelf life of shampoos but have been shown to mimic estrogen, potentially disrupting hormone balance.
  • Parabens have also been found in breast cancer tissue, raising concerns about their long-term health effects.


3. Phthalates


  • Often used to enhance fragrance, phthalates can be absorbed through the scalp and have been linked to endocrine disruption and reproductive health concerns.
  • They are sometimes hidden under the ingredient "fragrance," so look for shampoos labeled "phthalate-free."


4. Formaldehyde & Formaldehyde-Releasing Preservatives (DMDM Hydantoin, Diazolidinyl Urea, Imidazolidinyl Urea, Quaternium-15)


  • These chemicals are used as preservatives but can release small amounts of formaldehyde, a known carcinogen.
  • They have been linked to scalp irritation, allergic reactions, and even hair loss.


5. Synthetic Fragrances & Dyes


  • Artificial fragrances often contain hundreds of undisclosed chemicals, some of which can be allergens or irritants.
  • Synthetic dyes (such as FD&C or D&C colors) are derived from petroleum and may contribute to skin sensitivity or irritation.


6. Silicones (Dimethicone, Cyclomethicone, Amodimethicone)


  • While silicones can temporarily smooth the hair, they also create buildup over time, weighing hair down and making it appear dull.
  • Non-water-soluble silicones can prevent moisture from penetrating the hair shaft, leading to dryness and breakage.

What to Look for Instead


If you’re serious about supporting hair growth and maintaining a healthy scalp, opt for shampoos that are:

✅ Sulfate-free – Look for mild, plant-based cleansers like coconut-derived surfactants.

✅ Paraben-free & phthalate-free – Choose shampoos that use natural preservatives like vitamin E.

✅ Fragrance-free or naturally scented – Essential oil-infused shampoos offer a safe, therapeutic alternative.

✅ Silicone-free – Instead of silicones, opt for lightweight, natural oils like jojoba or argan oil to smooth and nourish hair.

Making informed choices about hair care products can be just as important as incorporating essential oils into your routine. By switching to cleaner shampoos, you’re giving your scalp the best possible environment for hair regrowth—before, during, and after chemotherapy. 😊
