Amazon is truly a treasure trove of affordable beauty staples, especially during Black Friday. Sure, some use this time of intense savings to put a dent in their holiday shopping list, while others (including myself) are keen to give themselves a few presents. Amazon reviewers aren't shy in sharing their love for their favorite beauty essentials — especially when the price point is low — and Black Friday is the time to pick up this castor oil with a serious following.

Castor oil is an ingredient approved by both dermatologists and Helen Mirren. Dr. Marina Peredo, a New York City-based dermatologist and founder of Skinfluence, previously told InStyle that the oil contains "omega-6, omega-9, and vitamin E, which all have nourishing and hydrating factors." She added, "It is also an anti-inflammatory and antibacterial, and has humectant properties, which means it attracts moisture and keeps the skin hydrated."

Sounds like a dream oil, right? According to reviewers, the Kate Blanc Cosmetics Castor Oil, a cold-press variation that's currently on sale for just $9, is tops for treating dry skin and improving hair health, another potential dermatologist-backed benefit. With more than 39,000 five-star ratings on Amazon, the Kate Blanc oil was deemed a "need" by one shopper, who added, "I've been using it on my eyebrows, lashes, and on my hair (my hair is natural, very curly, and colored), and in a month, I can already tell a difference. My eyebrows seem much thicker; my hair is so soft, thick, and healthy. My lashes are looking thicker and longer."

Intended for use on the skin, lashes, and hair, the Kate Blanc oil comes with a glass dropper, for precise application, as well as tools for applying to the eyebrows.

"Though my eyelashes were already decently long, I'm seeing even more noticeable improvement after three months [of use]. They're longer and more voluminous, appearing darker as a result. My eyebrows are also growing in after being super patchy for many years due to over-plucking and pulling out hairs from stress," one reviewer remarked of their experience.

As for whether you can expect hair growth, Bridgette Hill, a certified trichologist and inventive colorist in NYC, told InStyle, "Indirectly, yes castor oil assists with cultivating the necessary environment, (when properly used) to nurture and support healthy hair follicles and hair fibers." But, she cautioned against using the oil if you have dandruff or if you experience irritation.

One shopper, who called the oil a ″forever favorite,″ returned to update their original Amazon review, adding, "I continue to use it every single night for my eye area skin and lashes." While another reviewer called it the ″best lash serum,″ adding, "My skin tends to be dry, so I am using it, sparingly, for an added night moisturizer. Overall a great product at a great price."
