My Buying Guides on Biosilk Silk Therapy Finishing Spray
When I first started looking for a finishing spray to tame my hair and add that perfect glossy finish, Biosilk Silk Therapy Finishing Spray quickly caught my attention. After trying it out and learning more about it, I wanted to share my experience and some tips to help you decide if it’s the right choice for you.
What Is Biosilk Silk Therapy Finishing Spray?
This finishing spray is designed to provide shine, smoothness, and frizz control, all while protecting your hair from heat damage. It’s infused with silk proteins that help strengthen and nourish your strands, giving your hair a silky, polished look. For me, it works like a lightweight veil that leaves my hair feeling soft without weighing it down.
Why I Chose Biosilk Silk Therapy Finishing Spray
I was looking for a product that could do more than just hold my style. I wanted something that would improve my hair’s texture and health over time. The silk protein formula stood out because silk is known for its smoothing properties and moisture retention. Plus, it promised heat protection, which is a must for me since I often use styling tools.
Key Benefits I Noticed
- Shine and Smoothness: My hair looked glossy but natural, not greasy.
- Frizz Control: Even on humid days, my hair stayed tame.
- Lightweight Feel: It didn’t make my hair stiff or sticky, which is important for all-day comfort.
- Heat Protection: I felt confident using my flat iron after applying the spray.
How I Use It for Best Results
I spray it lightly from about 10-12 inches away on dry hair, focusing on the mid-lengths and ends. I avoid the roots to prevent any heaviness. After spraying, I gently run my fingers through my hair to distribute it evenly. It works great as a final step after styling or even on second-day hair to refresh shine and control flyaways.
What to Consider Before Buying
- Hair Type: If you have very fine hair, use sparingly to avoid weighing it down. For thick or coarse hair, it helps tame frizz nicely.
- Scent: It has a light, pleasant fragrance, but if you’re sensitive to scents, it’s good to test first.
- Price Point: It’s a bit of an investment, but a little goes a long way, so it lasts quite a while.
- Ingredients: If you prefer all-natural products, note that this contains some synthetic ingredients alongside the silk proteins.
Where to Buy and What to Look For
I found it easily available online and in beauty supply stores. When purchasing, check for sealed packaging to ensure freshness. Sometimes, bundles or kits include the finishing spray along with other Biosilk products, which can be a great value if you want a complete hair care routine.
