It combines professional-grade technology with nutrient-infused plates to deliver salon-quality results at home, making it an excellent choice for daily users and frequent travelers alike.
What sets this straightener apart is its keratin and argan oil infused ceramic plates. Unlike typical flat irons that simply apply heat, these nutrient-rich plates actively condition hair while straightening, leaving strands noticeably shinier and smoother. The iron heats up in seconds and glides effortlessly through hair without pulling or snagging, straightening thick or curly hair in just a few passes. Users consistently report that results look like they just stepped out of an expensive salon, with shine that lasts all day.

Buying Guide: What to Look for in a 1.5 Inch Flat Iron
Plate Material: Ceramic vs. Titanium
Plate material directly affects how heat transfers to your hair and the final smoothness. Ceramic plates, like those on the CHI models, heat evenly and emit far infrared heat that gently dries hair from the inside out. They reduce frizz and add shine, making them ideal for fine to medium hair that is prone to damage.
Titanium plates, as found on the BaBylissPRO, heat up faster and maintain a higher temperature for coarse or thick hair. They glide effortlessly without dragging. If you prioritize speed and high heat, titanium is a strong choice. For a deeper look at different plate types, check our straighteners category for more comparisons.
Temperature Control and Range
Adjustable heat settings let you tailor the iron to your hair’s needs. Fine hair requires lower temperatures around 300°F, while coarse hair may need up to 450°F. The CHI Original Digital offers five digital settings with a clear display, while the BaBylissPRO provides five precise heat levels as well. A wide range ensures you can safely style without overheating.
Look for models with fast heat up and consistent recovery. Both the BaBylissPRO and CHI irons heat in under 60 seconds, which is convenient for busy mornings. For those with shoulder length hair, our best straightener for shoulder length hair guide offers tailored advice.
Plate Width and Floating Design
At 1.5 inches wide, these plates provide excellent coverage for medium to long hair. They reduce the number of passes, lowering heat damage. Floating plates add spring tension to keep even pressure across the hair, preventing snags and ensuring a smooth glide. The BaBylissPRO The Ultra Sleek features full floating titanium plates, while the CHI Classic has floating tourmaline ceramic plates.
If you have short or pixie cuts, a 1.5 inch iron may be too wide. For that case, see our best mini straightener for short hair recommendations. But for longer styles, wide plates are a time saver.
Extra Features: Cord Length, Dual Voltage, and Warranty
Professional swivel cords (9 ft or longer) allow freedom of movement during styling. Dual voltage is essential for travelers, and the BaBylissPRO model includes it. Warranty length also matters: BaBylissPRO offers a limited 2 year warranty, while CHI provides standard coverage. For medium length hair, the best straightener for medium length hair guide compares similar features.
Final Thoughts
After evaluating the top contenders, the BaBylissPRO The Ultra Sleek Flat Iron stands out for its rapid heat up and titanium plates that tame thick hair quickly, while the CHI Original Digital Ceramic Hairstyling Iron excels in gentle, shiny results for fine to medium textures. Both deliver professional performance and are worthy of your styling routine. Choose based on your hair type and priority: speed versus gentle care.

What hair types are best suited for 1.5 inch flat irons?
