Schwarzkopf OSiS+ Flatliner Flattening Iron Serum & A Little About My Hair

Schwarzkopf OSiS+ Flatliner Flattening Iron Serum & A Little About My Hair

Okay so the last weekend was very different for me as I got my hair permanently straightened. Yes, I have done a lot of time with Philips, Morhy Richards and Remington flat irons, I own a ton of hair serums and heat defense sprays. But last december, In Pune I went to Lakme salon to get my hair done, when the stylist offered me this spray to use prior to flat ironing. now that I have got my hair chemically relaxed ad straightened, I thought let me share this product here.I am doing a post on my hair straightening experience super soon…especially for Jomol.

“Give hair a boost of moisture and strength with hydrolised silk and wheat proteins.

I took the hair pictures long back immediately after using this spray and flat ironing, the results were, like you can see very meh! I was so disappointed with this product that I had to share this here, since I did put in a lot of money into it, and regretted even more because I already own a lot of heat defense sprays.

Let me tell you what I expected from this spray, I had asked the stylist to give me something that would make my hair look more straight after flat iron and also make them last long, but I think what this product delivers is just a coating on your hair to protect against heat damage, may be the product is claiming  just that but asking for a little added shine is not criminal you see…but this did not do anything for the same.

I have dry, thick and curly hair, more like beach waves, to let you know more I am sharing some pics with my hair at its worst, please bare with it, I have always wanted straight hair and now I have it finally chemically straight for sometime. I was worried about the damage caused by repeated flat ironing.

My Original hair and mildly straightened hair without the spray:

What you get in this can is huge, a great spray nozzle, very easy to use, you can even lock it after use and carry it around safely. The spray is a actually a “spray” and not a serum and it did not deliver anything in terms of more straight hair, longer lasting straight hair , shiny hair nothing! I think it must have prevented a little heat damage, that’s it!

The only positive thing I liked about this is that it did not make hair greasy very soon, and the hair were straighter for longer, like a little longer. You need to go easy with spraying it or else you might get greasy hair.

See how it did nothing for my flat iron session:

Now that I have chemically straightened hair, let me show you my original bad hair day vs my permanent straight hair:

original vs straightened hair


And now finally see the difference from the above flat iron and the below permanent hair straightening effect, me super happy!

I say skip this spray, buy any other heat defense spray half the rate, it should work just fine.Like me if you are fed up of flat ironing every single time, consider my next post on my experience with permanent hair straightening. How many of you are interested getting their hair done soon?:D

  3. Me loving the straight look on you Neha! Its so easy peasy to manage isnt it? Which rebonding treatment did you go for? Also, for someone with thick hair it has come out really well without any kinks and unevenness. My last rebonding was 2yrs back – now you have tempted me to get it done again 😀

  11. I have wavy hair like yours too Neha and I use hair iron once in a while. I am glad I read this post, it reminded me to use protectant which I skipped all these time. =) I’m planning to have is straightened in 3 months I guess. I’d love to read your review on permanent straight hair treatment. =)

  12. i am so getting this one NEHA 🙂 .. and my my ur hair looks saloonish … .. loved it and far better than ur bad hair dayzz hahah .. what a tranformation.. i like straight hair on your a lot 🙂

  13. Hey Neha… Nice review… I have used a shampoo, conditioner and serum from schwarkof and i hated them except the shampoo.. i got it after i did hair smoothening.. i returned the serum immediately.. i would never go to this schwarkof again..

  14. ur hair looks beautiful before n after… since u have straightened it now.. do deep condition from the beginning itself so the smoothness will last for some more months.. dont forget to oil your hair.. i didnt do it n listened to the stylist but ending up losing the smoothness and shine soon… man i shud write an article about aftercare.. hehehe

  15. I too got my hairs permanently straightened around 7 months ago…ma natural hairs have grown now till my ears but its still straight as my hairs were naturally bit straight till ears and wavy from ears..!!

    i dont really care much coz i had t get rid of the volume so i like this style 😀

  22. I think i totally love your hair neha. I feel to be blessed with straight here because people with curly hair have high maintenance. Thank you so much for the heads up. I would have loved to give this product a try. I sooo loved your blue eye makeup in your pic. You looking pretty even though I can’t see your completely.:)
