Alternatives to Consider
Overview
Only Curls Shine & Define Serum proves you don’t need silicones for impressive shine. This blend of natural oils—argan, jojoba, and sweet almond—delivers a glossy finish without the buildup concerns that come with silicone-based serums. It’s designed as a finishing product to add that final polish to styled curls.
Key Ingredients Breakdown
- Argan Oil - The lightweight star that adds shine without greasiness. Rich in vitamin E and fatty acids.
- Jojoba Oil - Structurally similar to the scalp’s natural sebum, making it easily absorbed without residue.
- Vitamin E - Provides antioxidant protection and enhances the conditioning effect.
- Sweet Almond Oil - Emollient oil that softens and smooths the hair cuticle.
What We Love
- Genuine shine - Rivals silicone serums for gloss
- Silicone-free - CGM-friendly and no buildup worries
- Lightweight - Won’t weigh down fine hair when used sparingly
- Multi-use - Works on wet or dry hair
- Pleasant scent - Subtle and not overwhelming
- A little goes far - The 50ml bottle lasts ages
What Could Be Better
- No hold - Purely a finishing product
- Easy to over-apply - Less is definitely more
- Small bottle - Wish it came in a larger size
- Can look greasy if overused - Requires careful application
How to Use
On Styled Hair (Recommended)
- Wait until hair is fully dry
- Dispense 1-2 drops onto palms
- Rub hands together
- Scrunch gently through ends and mid-lengths
- Avoid roots unless you want added shine there
On Wet Hair
- After styling products, add 1-2 drops
- Apply with praying hands
- Focus on ends
- Diffuse or air dry as normal
Pro Tip
Start with just one drop. You can always add more, but too much oil is difficult to fix without washing.
The Verdict
At a mid-range price point, Only Curls Shine & Define Serum is excellent value for a finishing serum. It does exactly what it claims—adds shine and smooths frizz—without the silicone-related concerns. The natural oil blend is well-formulated and suitable for most curl types when used appropriately.
