When it comes to silky, frizz-free hair, keratin treatments are the holy grail but not all are created equal. The Keratin Blowout (Brazilian Blowout) and Traditional Keratin Treatment may sound similar, yet they work very differently. One offers a quick, lightweight smoothing fix perfect for fine or wavy hair, while the other gives long-lasting straightness that deeply repairs and nourishes thick or curly hair.In this article, we break down the key differences, longevity, aftercare, and results of both treatments, helping you find which one’s truly made for your hair type and lifestyle.
Long healthy, smooth and shiny hair is the dream of many, but due to today's polluted air, hair tends to become frizzy, rough and dull. So, what is the solution to get that dreamy shine? There are many treatments available, but the most common and effective one is the keratin treatment. This keratin treatment is classified into two categories ''keratin blowout'' and ''traditional keratin treatment''.

Keratin blowout refers to the smoothing treatment which makes the hair sleek, shiny, and frizz-free without changing the natural texture of the hair.
In this procedure the hair strands are coated with keratin-based formula, which fills in the damaged areas of cuticle.
After application the formula is sealed using a flat iron, locking in the smoothness and shine. This blowout is lighter ad more flexible and does not make the hair pin straight instead it keeps some natural waves or curls, and the results lasts up to 8-12 weeks depending on the hair type and aftercare.
![Smoothening]()
It refers to the deep smoothening and straightening of hair in which natural keratin protein is infused deep into the hair shaft to repair damage, reduce frizz and creates a sleek, polished finish.
In this procedure stronger keratin formula is used unlike brazilin blowout, this procedure smoothens the cuticle leaving the hair straighter and softer.
Avoid washing, tying or tucking the hair for about 48 to 72 hours after the treatment for keratin to settle in fully.
In comparison to the blowout, this treatment has longer lasting results, usually around 3 to 5 months making it easy for the people having frizzy and thick hair type.
The best treatment totally depends on the individuals hair type, texture, and overall condition. For the thin or color-treated hair keratin blowout(Brazilian Blowout) is safer option. As this treatment prevents the hair from breakage and frizz instead giving shine to the hair.
People having thick, coarse or very frizzy hair, traditional treatment is recommended for them because it provides deeper smoothing and linger lasting results.
As a lot of strong chemicals are used during this procedure so it should be done by professional stylist to avoid overprocessing or damage. Always take advice from the expert for any kind of hair condition or tips before any kind of treatment.

After getting these treatments maintenance is the key to keep the hair shiny and healthy for long period as possible. Start using sulfate-free and sodium chloride-free shampoos and conditioners , as harsh cleansers can take away the keratin coating and shorten the treatment lifespan.
Wash your hair 2 to 3 times a week to preserve the results. Swimming can also weaken the treatment and can cause dryness. Always wear a cap or apply conditioner for protection.
These are some basic steps to follow daily to keep your hair shinny and glossy.
