Product Information
Full details
The L'Oréal Professionnel Keratin Alpha Sleek Hair Serum is designed for adults seeking long-lasting smoothness and frizz control. Its key benefit is providing up to two weeks of flyaway control and glass-like shine with a heat-activated formula. A potential caveat is that optimal results require heat styling (blow drying and flat ironing). This lightweight, leave-in serum offers protection against humidity and thermal damage up to 230°C, featuring a 5% Keratin Sealer complex for a fuller, healthier look and up to five days of mirror-shine and smoothness.

FAQs
How long do the smoothing effects last?
Instrumental tests show results lasting up to 10 washes, with individual smoothness and frizz control lasting up to five days and flyaway control up to two weeks.
Can I use this serum on dry hair?
The serum is designed to be applied to towel-dried hair and activated by heat styling. Applying to dry hair may result in uneven distribution and suboptimal results.
What is the heat protection limit?
The Keratin Alpha Sleek Hair Serum protects hair from thermal damage up to 230°C.
Does this product contain actual keratin?
The serum contains a 5% Keratin Sealer complex, which works to seal the hair's natural keratin structure for smoother, longer-lasting results.
Can I skip the flat ironing step?
While blow-drying activates the product, flat ironing is recommended for longer-lasting results and optimal sleekness. Skipping it may reduce the duration of the smoothing effects.
Is this serum suitable for color-treated hair?
The product is designed for general use and offers protection. However, always patch-test on a small section if you have concerns about color-treated hair.
How much product should I use?
For thin to medium hair, use 2-4 sprays. For thicker hair, use 6-8 sprays. Distribute evenly from mid-lengths to ends.
Troubleshooting
Hair feels sticky or heavy after application.
You may have used too much product. Try reducing the amount used, especially on finer hair sections, and ensure even distribution from lengths to ends.
Results not as smooth or long-lasting as expected.
Ensure hair is properly detangled and towel-dried before application. Also, confirm that heat activation through blow-drying and flat ironing was sufficient.
Product seems difficult to distribute evenly.
Shake the bottle well before use and rub hands together thoroughly to create a fine mist before applying to sections of hair. Ensure even saturation from mid-lengths to ends.
