Botanic Hearth Rosemary Hair Oil for Hair Growth — 16 fl oz Cold-Pressed with Biotin & Castor

Botanic Hearth Rosemary Hair Oil is a 16 fl oz, cold-pressed blend with rosemary, biotin, castor and jojoba oils formulated to nourish the scalp, strengthen strands and promote thicker-looking hair when used regularly.

This full-size bottle delivers a concentrated mix of natural oils in an amber, sunlight-protective container and includes a precision applicator to place oil directly at the roots. The lightweight, non-greasy formula is free of synthetic colors and fragrances and is intended to be used as part of a scalp care routine—especially effective when paired with a silicone or bristle scalp massager to improve distribution and circulation.

How do I use this oil to improve scalp condition and hair appearance?

Apply the oil directly to the scalp using the precision applicator, sectioning hair for even coverage. Massage gently with fingertips or a scalp massager to help spread the product and increase contact with follicles.

• Section hair into narrow parts and apply 1–2 drops per spot for targeted delivery.
• Massage 3–7 minutes with fingertips or a silicone scalp massager for optimal absorption.
• Leave on 30 minutes to overnight depending on preference; shampoo and condition afterward.

What ingredients are in the formula and why are they included?

The blend combines cold-pressed rosemary oil with biotin, castor and jojoba—each chosen for specific hair and scalp benefits. These ingredients are plant-based and selected to moisturize, fortify hair fibers and help maintain a balanced scalp environment.

• Cold-pressed rosemary oil: concentrated essential oil to support scalp care routines.
• Biotin: a water-soluble B-vitamin included to support hair-strengthening formulations.
• Castor and jojoba oils: thicker and lighter carrier oils that hydrate and condition strands.

Is this product safe for color-treated or chemically processed hair?

The formula is presented as color-safe and free from mineral oils, paraffin, and synthetic dyes or fragrances, making it suitable for most color-treated and relaxed hair types. Always perform a patch or strand test if you have recently colored or chemically treated hair to confirm compatibility.

• Free from synthetic colorants and fragrances to reduce risk of immediate reaction.
• Amber bottle shields oils from light, preserving potency for safer use over time.
• Designed to work with a scalp massager to minimize excess product buildup on strands.

How often should I use the oil and can it be combined with other products?

Use frequency depends on your scalp and hair needs: weekly to several times per week is typical for many users. The oil layers well under treatments and can be rinsed before applying styling products to avoid excess buildup.

• Start with once or twice weekly and increase frequency based on scalp response.
• Use as a pre-shampoo treatment to remove with regular cleansing afterward.
• Compatible with conditioners and leave-in treatments when used sparingly on the lengths.
