Frequently Asked Questions

The keratin shampoo has 5% formaldehyde and is effective in straightening type B and type C curls.  This shampoo will also cleanse your scalp thoroughly and let your hair absorb the keratin. This will make your hair shiny and  increase your hair strength.

Both 5% and 12% formalin hair shampoos serve the same purpose but the longevity of each formulation is different. The 5% formalin keratin treatment lasts for a shorter period of time than the 12% formalin keratin formulation. The former treatment is suitable for those with wavy or slightly curly hair whereas the 12% formalin treatment is ideal for people with type D curly hair.

Yes. With regular use, this combination will make your hair smooth and straight. Keratin will make your hair strong and straight while pentanol, murumuru oil will add volume and lustre.


  • The shampoo consists of low molecular weight keratin molecules that have higher binding affinity with your hair and have greater number of essential amino acids. Your hair cuticles effectively absorb the keratin molecules and strengthen your hair.
  • It enables your hair follicles to absorb keratin, which in turn, reduces friction between hair shafts. Decrease in friction prevents hair breakage and split ends. The conditioner smoothes curly and unruly hair to provide you with straight and manageable tresses.
  • This shampoo and conditioner combo is perfect for those who are just beginning to explore keratin straightening treatments. Since the keratin concentration us 5%, it will give you silky straight hair without making it unnaturally stiff.
  • The conditioner will prevent your hair shafts from breakage when you scratch your head or add any physical strain on your hair by holding it up with rubber bands.
  • The shampoo and conditioner duo will be ideal for those with Type B and Type C hair since the keratin concentration is 5%. If you have type D curly hair, we would suggest you to go for a shampoo that has a higher concentration of keratin.

Each of the products in our kit has a unique function and effectively treats your hair. Though you can use them separately, we would suggest you use them together for better results. Studies show that our hair responds better when it is treated with the same line of products.


  • Hydrolyzed keratin-  Keratin is the building protein of our hair and is responsible for imparting strength along with elasticity to our hair strands. It protects the hair from breakage, prevents split ends and also helps in dealing with hair stress. It smoothes your hair texture by forming new cells in hair strands  which overlap and cause friction with other strands. Hence, it also controls frizz and gives a straight and shiny appearance to your hair. Since hair is composed of 95% protein, adding keratin to your scalp helps your hair grow faster.
  • Glycerin- Glycerin is one of the most effective humectants that retains and absorbs moisture from the environment into your hair. It prevents your scalp from flaking or itching sensations, which get aggravated, especially during the winter.
  • Cetearyl alcohol- Unlike common misconception, cetearyl alcohol is a highly nourishing and beneficial fatty alcohol. It acts as an emollient and helps to soften your hair. Unlike common misconception, cetearyl alcohol- is non-inflammatory and does not cause any damage to the hair.
  • Step 1- Wash your hair with the PURC Keratin shampoo to get rid of the accumulated dirt and enable your hair follicles to absorb keratin molecules.
  • Step 2-  Gently pat your hair with a towel and dry with your blow dryer. Keep your dryer at the lowest heating temperature.
  • Step 3- Put on a pair of gloves and part your hair into four sections
  • Step 4- Use your hand to spread the PURC Straightening Treatment on your scalp. Then, use a wide tooth comb to distribute the contents evenly.
  • Step 5-  Take a flat iron and set it at a temperature of 300-400 degree Fahrenheit if you have fine hair. If you have thicker hair, set the temperature at around 450 degree Fahrenheit.
  • Step 6- Take an inch of your hair and use your flat iron to straighten it. Repeat the process until the entire length of your hair is smooth.

The treatment will provide you long lasting results. You can use the treatment once in two or three weeks to see the results. However, if you are often exposed to pollution or are experiencing rapid hair loss, we would recommend you to use the treatment once a week.

You can feel the difference from the first wash itself. However, hair care products do take a little time to completely show the results. To get the actual results from the intense nourishment kit, you would have to wait for about two weeks to know the actual effect it has on your hair.

Yes. Since this line of keratin treatment contains 5% formalin, it should not be used by pregnant women or on individuals who have extremely sensitive skin. Do a patch test before applying the treatment on your hair.
