What is the Difference Between Keratin and Cysteine Treatment?

The main difference between keratin and cysteine hair treatments lies in the chemical composition and safety concerns. Both treatments aim to straighten and smooth hair, but they use different methods and ingredients:

Keratin Treatment:

• Uses keratin, a natural protein found in hair, to straighten and smooth hair.
• Contains harsh chemicals like formaldehyde, which can cause skin irritation, nausea, and eye irritation.
• Lasts for 3-6 months.
• Leaves hair smooth and shiny.

Cysteine Treatment:

• Uses cysteine, a nonessential amino acid that occurs in keratin and other proteins.
• Free from harmful additives like formaldehyde, making it safer for everyone, including pregnant women and children above 12 years.
• Lasts for up to 6 months.
• Gently relaxes the hair's natural curl without the use of harmful additives.

In summary, cysteine treatment is considered safer than keratin treatment due to the absence of formaldehyde and other harsh chemicals. However, it is more expensive and has a slightly shorter longevity. Both treatments straighten and smooth hair, but cysteine treatment is more suitable for those who prioritize safety and do not want to expose themselves to potentially harmful chemicals.

Comparative Table: Keratin vs Cysteine Treatment

Here is a table comparing the differences between keratin and cysteine treatments:

Keratin treatment is a chemical procedure done at a salon to straighten hair, containing formaldehyde, which can cause health issues. Cysteine treatment, on the other hand, is a protein hair treatment that uses a non-essential amino acid found in keratin to straighten and strengthen hair without harsh chemicals. It is safer for pregnant women, children, and those with sensitive skin. However, cysteine treatment is more expensive and has a shorter longevity compared to keratin treatment.
