1. Rosemary Oil
It’s no coincidence that rosemary oil is one of the most common ingredients added to hair serums and oil blends, because studies exist that show major benefits from massaging your scalp with this fragrant oil on a regular basis. One 2015 study compared rosemary oil with minoxidil in patients with androgenetic alopecia. After six months of tracking patients who used both it was reported that both groups saw hair growth outcomes. What’s even more interesting: the group applying rosemary oil didn’t face side effects like irritation, which can be common with Minoxidil.
When applying rosemary oil, make sure to mix with a few drops of a gentler carrier oil like coconut or jojoba oil.
2. Castor Oil
You can find castor oil marketed for all kinds of hair growth products, including eyelash and eyebrow serums. Although research and studies into this oil and its effectiveness are limited, it’s an old-fashioned traditional remedy that is rich in nutrients and like fatty acids and vitamin E and can stimulate hair follicle growth and may thicken hair. A small 2013 study published in International Journal of Trichology found that castor oil can help with eyebrow growth, but it isn’t known if the same outcomes can apply to the scalp.
3. Oils With Peptides
Peptides have become the talk of the town, including where hair growth is concerned. Peptides are short chains of amino acids that have been shown to have a positive effect on hair follicles.
The Ordinary Multi-Peptide serum for Hair Density is an affordable hair oil that incorporates the powers of peptides. Its key ingredients include:
-Redensyl (Givaudan): Targets stem cells and human fibroblasts from the derma papilla to improve hair density.
-Procapil (Sederma Inc.): Increases blood flow in the scalp, which allows the hair to be well nourished, resulting in appearance of thicker hair.
-Baicapil (Provital): Increases the look of hair density.
According to several reviewers, it works! Here’s what one reviewer had to say: “I don’t usually leave reviews, but since this serum worked for me I think it would be helpful for other women to benefit from this product. I have been using it for a month now. I started noticing my hair falling a lot due to stress so after reading about the ingredients I decided to give it a shot. After a month I can tell the growth is noticeable specifically in the hairline and in the areas where I have been applying the serum religiously every night before bed. I love the fact that doesn’t have a smell and it doesn’t leave my hair greasy at all. I would say consistency is key, don’t expect results if you don’t use it everyday.”
