What is rosemary oil?

Known as one of the strongest culinary herbs in the world, rosemary is also linked to natural health care in general. It’s taken from its natural Mediterranean habitat before the oil is used for improving our foods and our medicines. This has become a very strong solution for those who are looking to try and find ways to help improve the condition of their body.

It’s used regularly in beauty and in health products, though; it’s not just a brilliant flavor to add to your foods. How effective, though, is rosemary oil on hair? This has become a major talking point in recent years. Claims are made about essential oils all the time, so how well do claims about rosemary oil stand up to scrutiny? What benefits can you expect to see if you use rosemary oil on your hair?

Rosemary Oil For Hair: Benefits

As noted above, rosemary oil has been remarked as a reliable hair treatment solution for some time. It’s become the common choice for many people, offering a reliable intake of antioxidants to working to help reduce inflammation. How, though, can taking rosemary oil help your hair? What kind of benefits are being linked to the use of rosemary oil in human hair?

  • Rosemary is known to help promote nerve growth and improve circulation, boosting hair growth.
  • By helping to push more blood through the system, rosemary oil can help promote hair growth.
  • It’s also been linked to being able to combat problems such as dandruff or itchy scalps.
  • Though little clinical evidence supports this, rosemary has been linked to preventing hair loss

Rosemary Oil Side Effects

The only thing to worry about with rosemary oil comes down to the potency and the direct contact with eyes. If you get this in your eyes, rinse it out ASAP – as you should with any essential oil.

Try and avoid making too much of this oil in one batch. Excessive use on the scalp can lead to problems like skin irritation. Simply dilute it with a carrier oil and you can avoid this. 

We recommend that you should try and avoid using rosemary oil when pregnant, too. Other than that, though, health risks and side-effects are not well very known about rosemary oil.
