The liquid extracted from flowers has been used in some cultures to treat certain medical problems, keep insects away, and in aromatherapy. Undoubtedly, its purple-toned leaves are recognizable both by sight and smell, but its distinguished color and aroma are not its only characteristics. What is it useful for on the scalp? Does it promote growth?
When applying any product to the hair, its effectiveness in promoting hair growth is important. Presumably, in the case of lavender, it could be a reality, according to Healthline, which has noted benefits in counteracting alopecia and baldness, based on a 2016 study that showed increased thickness and speed of hair growth in a small group of people.
Does it fight dandruff? Healthline attributes antifungal and antimicrobial properties present in the scalp to lavender. One of the most common fungal infections is dandruff; therefore, lavender could help reduce symptoms such as itching and even eradicate the condition, although more studies are needed in this regard.
Does it eliminate lice? A study conducted in 2011 concluded that applying lavender essential oil to the hair helps in preventing lice. Healthline identifies it as a potential eradicator of these parasites but warns that it should not replace medications and products used against such infections, being more of an adjunct.
Regarding hair hydration, Healthline highlights that lavender has a positive effect in combating dryness. The essential oil of the plant could help reduce inflammation of the skin due to irritation and itching; however, there are no citations from medical or scientific analyses regarding this.
Finally, lavender is attributed a relaxing effect in the aroma of this plant species. An experiment conducted in 2012 showed that inhaling lavender liquid decreased stress and improved people's mood.
As for side effects, allergic reactions such as nausea, vomiting, headaches, and chills are highlighted, among others. Regarding the application of lavender essential oil to the hair, it is recommended to massage the scalp by mixing it with coconut oil to reduce its concentration or adding it to shampoo in an appropriate proportion.
