Rosmarinöl für Haarwachstum: Was Experten sagen & was wirklich hilft

TikTok videos have popularized the idea of rosemary oil as a remedy for promoting healthy hair growth, with many users claiming it has led to longer and thicker hair. However, experts suggest that rosemary oil alone is unlikely to deliver substantial, lasting results.

The Complexities of Hair Growth

“Hair loss is biologically complex and emotionally fraught, so it’s easy to make simplifying or exaggerated claims,” explains Oma Agbai, a clinical professor of dermatology at the University of California, Davis School of Medicine. While some individuals may experience a modest benefit, she emphasizes that this is not comparable to the outcomes seen with evidence-based treatments.

What is Rosemary Oil?

Rosemary oil is an essential oil extracted from the rosemary plant. It’s frequently used in hair and skincare products due to its purported anti-inflammatory and antimicrobial properties. The theory behind its use centers on the idea that it can improve scalp circulation and reduce inflammation, potentially supporting hair growth. However, the scientific evidence supporting these claims remains limited.

Limited Scientific Evidence

Some studies suggest a possible, albeit small, effect on androgenetic alopecia, the most common form of hair loss in both men and women. Adam Friedman, professor and chair of dermatology at the George Washington School of Medicine and Health Sciences, cautions, “It’s not magic.”

Androgenetic alopecia is linked to androgens, particularly dihydrotestosterone (DHT). High DHT levels or increased DHT sensitivity can cause hair follicles to shrink, leading to thinner hair and a shortened growth cycle. While some research indicates rosemary oil might have a slight influence on reducing DHT, it hasn’t been definitively proven to reduce hair loss or promote significant, sustained hair growth.

there’s no conclusive evidence that rosemary oil helps with other forms of hair loss, including telogen effluvium (temporary hair loss due to stress, illness, or pregnancy), alopecia areata (patchy hair loss caused by autoimmune conditions), or scarring alopecia (which leads to permanent hair loss due to inflammation).

Why the Belief Persists

Much of the enthusiasm surrounding rosemary oil stems from a 2015 study that gained traction on social media. This study compared a rosemary oil solution to 2-percent minoxidil (commonly known as Rogaine) and showed similar results in men with androgenetic alopecia. However, dermatologists point out that the improvements were modest, the study involved only 100 participants and lasted only six months, and there was no placebo group. This makes drawing definitive conclusions difficult.

oils can improve hair’s shine and reduce breakage, creating the appearance of fuller hair. In some cases, hair loss may resolve on its own after a few months, and this improvement could be mistakenly attributed to the oil.

How to Use Rosemary Oil

For those interested in trying it, it’s recommended to mix a few drops of rosemary oil with a carrier oil, such as coconut or jojoba oil, and massage the mixture into the scalp. It’s generally well-tolerated and rarely causes irritation. However, experts emphasize that it should be used as a complement to, not a replacement for, proven medical treatments.

Other Factors and Proven Treatments

Beyond products, important factors include a balanced diet, sufficient sleep, and stress management. Addressing deficiencies in nutrients like iron, zinc, vitamin D, or protein is also crucial. Avoiding very tight hairstyles (such as tight braids or ponytails) is recommended, as they can lead to traction alopecia.

Dermatologists recommend the following treatments with scientific backing: Minoxidil (oral or topical 5 percent), which is extensively researched and effective for many people with androgenetic alopecia; Finasteride, which reduces DHT and promotes hair growth (primarily used in men); Spironolacton, often used in women, especially in combination with other treatments; and Dutasteride, which is more potent at reducing DHT and is used off-label for hair loss.

Frequently Asked Questions

What is androgenetic alopecia?

Androgenetic alopecia is the most common form of hair loss in men and women, linked to androgens, particularly dihydrotestosterone (DHT). High DHT levels or increased sensitivity to DHT can cause hair follicles to shrink.

What was the key finding of the 2015 study on rosemary oil?

The 2015 study compared rosemary oil to 2-percent minoxidil and showed similar results in men with androgenetic alopecia, but dermatologists caution that the improvements were modest and the study had limitations.

Are there other forms of hair loss that rosemary oil might not help with?

Yes, there is no conclusive evidence that rosemary oil helps with telogen effluvium, alopecia areata, or scarring alopecia.

Considering the complexities of hair loss and the limited scientific evidence, what role do you think individual expectations and anecdotal evidence play in the popularity of remedies like rosemary oil?
