Keratin Alpha Sleek - Siero

Use a small amount

I found this L’Oréal serum to leave my hair sticky and unmanageable. So after trying it and using a lot less it was slightly less sticky and kept my hair straight and manageable for longer than normal. I had shine and lot less frizz than usual .

Great product for taming frizz and getting that sl

Smooth, frizz free hair for up to 2 weeks with a lasting shine. Great for taming unruly hair and boosting manageability. The spray aspect of the bottle is great as it’s mess free and the application couldn’t have been easier. I have quite long hair at the moment and I used around 8-10 sprays. So this bottle will last quite a while

Good but don’t like the smell

I like how it works and it does truly smooth my hair but I’m not a big fan of the smell. It smells really strong and similar to bleach. Other than that it is good. I like the packaging too.

Five days straight smooth hair ❤️

L'Oréal professional keratin Alpha Sleek serum is a leave in serum for smooth, frizz free hair. Reprograms the hair for long lasting frizz control. Glass shine and easier styling in half the time. The serum seals the hairs keratin structure for up to 5 days straight smooth hair. Fights against 80% humidity and doubles up as a heat protectant too! The serum is heat activated with either a hair dryer or a straightener for long lasting results. Just divide the hair into sections, spray the serum into your hands and glide through sections until hair is coated before heat styling for best results. I used a straightener and I can definitely see a huge difference. My hair felt significantly smoother, easier to style and did last days before I needed a wash day! I love that the serum is colourant and alcohol free. Easier manageable glossy hair, an amazing serum ❤️

perfect for a straight look with no frizz

great serum and works best with heat for a glossy look. Worth it’s value as a little goes a long way. Makes your hair smell light and salon-fresh. Apply to damp hair, don’t rinse, and style with heat.

Easy to use

Such an easy product to use, simply wash my hair and then spray onto it after. No harsh smells, good sized bottle, pretty purple colour so looks very nice. Heat activated so tends to work when using the hairdryer after washing.

Perfect hair care for a busy mum! So easy to use!

I recently tried L'Oréal Professional Paris Keratin Alpha Sleek treatment and I'm honestly so impressed with the results. My hair feels incredibly shiny and smooth even after 3 days of using it. Usually my hair starts to lose that fresh Sleek look after a day but this has really lasted. One thing I really love about it is there's no greasy heavy feeling my hair still feels light and clean. I'm just more polished. The product is super easy to use which is always a plus as I don't always have time for complicated hair routines as a busy mum. Another huge difference for me is the frizz control. It's great.

Smooth soft shiny hair

This was my 1st time off using this product and I found it to be good. Its so easy to use, i spray 4 sprays onto my hand and rub them together then applied to my hair starting with roots and worked down my hair to the ends, then I brushed it through before drying my hair with my hair dryer, its the heat from drying hair that activates the serum to work, I can say that my hair felt very soft and looked shiny, it tamed abit off frizz from split ends but not fully, i noticed no difference in volume to my very flat hair so why I dropped a star from the rating for my review. It is supposed to last up to about 10 washes before needing to use it again so you will get good value for money from it as it will last a while.. the serum does not leave a sticky oily feeling on your hands after applying it to you hair but will definitely need to wash them as my skin was very shiny. It seems to be a good product so I will continue to use it every 10ish days as happy with its results .

Greasy

Was excited to try this but I’ve been a little disappointed. I really like the bottle and idea behind it. Sprays onto my hair easily but sadly left it greasy. Didn’t absorb well. It feels soft but there’s no shine and just looks greasy so not ideal. Will try again but if it’s greasy I won’t be using it.

Amazing product

The serum is coming in a nice purple shade bottle with pump easy to use and very efficient. Have a nice soft scent which offers to my hair a soft and shiny texture. Have a good value raport quality and quality.

Shiny and sleek hair

It is advised to use this keratin sealer on towel dry hair. I find this serum to be light and non greasy. It requires heat to activate it. This is fine for me as I use a hair dryer and hot comb on my hair. I have afro 4C hair which gets very dry and frizzy. Using this serum does help to reduce the frizz. It also makes my hair feel very soft and more manageable. This is because my comb glides through my hair after using this hair serum. It's non sticky and has a very light floral scent to it. This is because it does contain parfum. I really like how it makes my hair soft and sleek. Sometimes after I have showered the steam makes my hair frizz, when using this serum it helps to reduce how much my hair gets frizzy.

Spring has sprung and I’m ready to face the world

I absolutely love this product, from its sleek, stylish packaging to the enticing, fresh, floral scent. It really packs a punch in the styling game! A few spritz’s of this little beauty and you are red carpet ready! It is easy to use, doesn’t leave greasy marks and leaves my locks feeling luscious and me ready to face the world.
