Choosing a keratin treatment
First, decide what change you want
“Keratin treatment” can refer to different services in salon descriptions. Some are intended to smooth hair and reduce frizz; others are presented as conditioning treatments intended to give hair a smoother appearance or more shine. The name alone does not tell you whether the aim is to straighten your hair, which products are used, or whether heat is applied during the treatment. Before booking, find out exactly what the salon offers.
Think about what matters most to you: keeping your hair’s natural shape, reducing frizz, or achieving a straighter look. If you want to preserve your curls, the word “smoothing” alone may not be precise enough. Tell the stylist what result you hope for and ask how the proposed service might affect your hair’s shape. It is just as useful to explain which changes you would not want.
Compare the process, not just the name
Keratin services may differ in the products used and how they are performed. Ask which specific product will be used, what the treatment is intended to do, whether heat will be applied, and what visual result is sought. If ingredients matter to you, ask for information about the product rather than relying on the service name alone. This makes it easier to compare options that appear identical at first glance.
Be cautious about promises to “restore” damaged hair. A cosmetic treatment may change how hair feels or looks, but it does not undo chemical processing that has already taken place and is not a treatment for the causes of hair damage. Ask what change is expected for your hair and what the treatment cannot change. A clear explanation can help you decide, but it cannot guarantee that the result will meet your expectations or that irritation will not occur.
Discuss your hair history before booking
Tell the stylist whether your hair has been dyed, bleached, straightened, or otherwise chemically treated. Mention if it breaks, seems fragile, or if you were unhappy with the result of a similar treatment in the past. This information helps you discuss the look you want and the limitations of the proposed service. If you are also planning to color your hair, ask what order the services should follow with the specific products being used.
When booking, check what is included in the service you choose and whether a separate consultation is planned beforehand. If you know you are sensitive to certain ingredients, tell the salon and ask for information about the product. Consult a qualified doctor about allergies, scalp conditions, or other health concerns. A salon consultation is not a substitute for a medical assessment.
Match preparation and aftercare to the service
There is no single preparation rule that applies to every keratin treatment. When booking, ask whether you need to prepare your hair in any way before the appointment and whether you should mention styling or hair-care products used recently. Follow the salon’s instructions and those for the product being used, rather than general advice about washing or avoiding products. If the instructions are unclear, it is worth asking for clarification before your visit.
After the treatment, ask for aftercare instructions specific to the service you received. Find out whether they cover washing, tying up, styling or coloring your hair, or the products you use. There is no need to buy special products in advance simply because they are labeled “for keratin.” Decide based on the instructions you receive, product directions, and what is relevant to your hair; do not assume that advice given for another keratin service applies to this one.
Consider the treatment’s limitations
Even after a detailed discussion of your hair’s condition, the same result cannot be promised for everyone. Hair’s starting appearance, previous services, the product used, and the desired change all vary. Before confirming your booking, ask whether the treatment is aimed more at a straighter look or a smoother feel. If you want only a subtle change, say so clearly.
Also ask which possible unwanted results the salon discusses before this service. No consultation can guarantee that they will not occur. If you experience severe irritation during or after the treatment, or notice other concerning changes in your health, consult a qualified doctor. You can tell the salon which service was performed and which product was used.
Frequently asked questions

What should I find out when booking?
Ask about the treatment’s purpose, the product used, whether heat is applied, and the aftercare required for that specific service.
Is it important to mention that my hair has been bleached?
Yes. It is part of your hair history and worth discussing when considering the limitations of the proposed service.
Can a keratin treatment be combined with hair coloring?
Discuss whether this is possible and the order of services with the salon, taking into account the products used and treatments you have had previously.
Does talking with a stylist eliminate the risk of irritation or an unwanted result?
No. It helps clarify the process and expectations, but it does not eliminate those risks.
