Step by step

When to stop and book a professional

DIY keratin treatments can be risky if you don't follow instructions precisely. If you are unsure about your skills or have particularly sensitive hair, it is advisable to book an appointment at a salon. Our providers document this care in their bios — see the My Hair Salons network for professionals near you.

Per the Professional Beauty Association, salons have access to professional-grade products, which tend to deliver superior results.

Cost: DIY vs salon

Aftercare tips

Post-treatment care is critical. Avoid sulfate shampoos to prolong the effects, as recommended by the FDA's consumer health guidelines. Brazilian Bond Builder is an excellent aftercare product for maintaining strength and shine between treatments.

Planning your next session

Generally, keratin treatments last about three months, but they can be extended with proper care. Regular check-ins with your stylist can help maintain your hair's health.

Common misconceptions

A keratin treatment is not a permanent solution; it is a smoothing process. Many people believe it straightens hair completely, which isn't the case for all hair types.

Product safety

Always check the ingredients for formaldehyde or its derivatives to ensure safe usage, as the FDA has expressed concerns about these components.

Factors Influencing The Price

The cost of a keratin treatment is not only about the price of the kit or salon charge. Hair length and thickness can significantly alter the cost; longer, thicker hair requires more product and time, thus raising the price. Some salons may charge an additional fee for especially long or dense hair, adding $50 to $100 to the final bill. Additionally, the type of keratin formula used can also influence cost. More advanced or specialized formulas, such as those for color-treated hair, are generally more expensive. Leaving a salon tip, typically ranging from 15-20% of the treatment cost, should also be factored into your budget.

Assessing Quality Before Booking

Choosing a quality keratin treatment requires scrutiny. Research salon reviews for feedback on stylist expertise and customer satisfaction. When considering a DIY approach, check online forums or beauty groups for peer reviews on specific kits. If viewing salon demos or consultations, observe the stylist’s knowledge of different treatment types and their experience in handling your hair type. Ask about the humidity of the salon’s environment, as it can affect hair characteristics. Ensure the selected kit or salon treatment comes with specific ingredient information to avoid damaging additives.

Questions to Ask During Consultation

Before booking a keratin treatment, several pivotal questions should be addressed during the consultation. Ask the stylist about their experience with your hair type and specific treatment options they recommend. Inquire about the longevity of the results and any associated costs beyond the initial treatment. Ensure they explain the post-treatment care process to you, including exact aftercare products and their cost. For those concerned about potential allergic reactions, it’s advisable to ask about doing a patch test. Lastly, ask for a full breakdown of charges, including expected surcharges for longer hair and any applicable discounts.

When Is Budget Option the Right Choice?

Choosing a budget-friendly keratin treatment might be a practical option under certain conditions. If you are trialing keratin treatments for the first time and unsure of the benefits, starting with a cost-effective DIY kit could prevent unnecessary expenditure. For those with less demanding hair types or those who stick to a meticulous aftercare regimen, a cheaper kit could achieve suitable results. If your primary goal is temporary frizz reduction rather than a long-term solution, the lower price option can meet basic needs without significant financial investment. Additionally, opting for cheaper treatments with complementary DIY practices like regular deep conditioning can extend results.
