Bonding Oil
Multi-use bonding oil for strength and shine
Part of the Strength (purple) range, this protein-free bonding oil is one of the more versatile products in the Curlsmith line — it works as a pre-shampoo hot oil treatment, a finishing oil over styled and dried curls, or an overnight strengthening mask. Rated 4.4 stars from nearly 1,000 Ulta reviews, and specifically recommended by Curlsmith for low-porosity hair, where its lighter oil base absorbs more readily than thick butters or heavier oils. One to two drops is genuinely enough for most hair lengths — start there and build up rather than applying freely, as it concentrates well. A good one to add if you want to work strengthening into your routine without committing to a protein-heavy cream or mask.
