Tanino Hair Treatment Side Effects-Informed Search Before You Do It
Published: 18 Dec 2024
Tanino hair treatment, or tanning plastic, is a great way to get rid of frizzy hair, leaving one with smooth and shiny hair, as it employs the use of tannins – natural compounds found in plants. Because there are no chemicals in it, it has gained popularity as a healthy substitute for chemical-based treatments. Even so, it’s essential to be aware of possible side effects before using Tanino, as with any other hair treatment. This article is dedicated to elucidating the contraindications of Tanino hair treatment and for whom it is most recommended, as well as crucial aftercare recommendations to prevent hair from becoming damaged and brittle.
What is Tanino’s hair treatment?
Treatment of hair with tanning hair treatment helps smooth hair with polyphenols sourced from plants. Tanino treatment is not like any other keratin treatment that requires certain chemicals since it’s a natural source that binds with hair, calms down wild strands, and makes one’s hair more manageable. Produced without formaldehyde, the bond is very mild. Traditional chemical straightening bows to tango-dominated treatments.
Adverse Reactions from Tanino Hair Treatment
Most people consider Tanino hair treatment as a less damaging procedure than other chemical treatments available on the market.

Nevertheless, it’s always prudent to be aware of the following Tanino hair treatment side effects:
1. Minor Inflammation of the Scalp
During or immediately after the treatment, mild inflammation of the scalp may be noted by some people, especially those with sensitive skin. So, every user can first use anti-allergic medication to minimize the scope of such a reaction or do a patch test. The irritation also can be due to the tannin of the treatment, or how it was administered, and can be avoided by talking to the stylist beforehand.
2. Roughness or Fragility
Another common Tanino hair treatment side effect includes roughness or fragility that may result from over-processing, trauma, or dry hair. To counteract the treatment’s smoothing effects, which allow the user to style hair more uniformly and cut down styling time, the user’s hair may require excessive moisture to avoid dryness. For best results, follow dry hair care tips such as using a hydrating shampoo and conditioner after the procedure.
3. Strong Odor at First
Another negative side effect of the treatment is that some users experience a strong smell that may be completely intolerable, and the odor may last for a few hair washes. The smell is much better than that of formaldehyde-based treatments, but it’s still unpleasant to the user, primarily due to it being quite pronounced as the treatment takes effect. Like other side effects, the odor usually goes away within a few washes.
4. Alterations in Curl Pattern – Possible Changes
Tanino treatment does not have a permanent effect on the hair structure, but can, however, relax the natural curls or waves, which in turn has the possibility of affecting the curl definition. This alteration is often short of permanence, but the long-term health and look of the curled hair should weigh the probability of having a looser and relaxed curl before proceeding with the Tanino treatment process.
5. Allergic Reactions – An Affliction to Consider
There is a possibility of having an allergy to the tannins or any other ingredient present in the treatment, although such instances are rare. Usually, people who are allergic to such components tend to complain of skin itching or analyzing, or whether there is a rash around the scalp or not, which warrants initial inquiries. Carrying out a patch test before the treatment may assist in averting any possible allergies.
6. Volume Loss – A Disadvantage
By the very nature of the process of applying Tanino treatment, where frizz reduction is the target, there is a likelihood of volumetric loss. As tanning effects are very much appreciated by people who deal with frizziness or thick hair, others who prefer a volumetric hair appearance after treatment may feel that the treatment has had an unwanted effect of flattening their hair.
7. Brief Color Washout – An After Effect
If, for any reason, the hair coloration treatment had been carried out, the Tanino treatment is likely to have minimal adverse color impact, particularly to those with bright or new color hair strands. If at all, color has to be avoided; checking with the stylist as to when color treatments can be done after a tanning process is performed, plus utilizing a color-safe, sulfate-free shampoo is strongly advocated.
Who Should Avoid Tanino Hair Treatment?
Tanino hair treatment is generally safe on the majority of hair types, which can be a source of hair rejoice. For best results, it’s helpful to follow specific types of hair tips to ensure the treatment suits your unique texture and condition.

People with Severely Damaged Hair:

People with Sensitive Skin or who Suffer from Allergies
In case the skin is generally sensitive or certain allergies are known, please ask for a patch test as well so you would not react to the tannins.
People Who Love Their Curls
For people with Curly hair who want to maintain certain tight curls or curl patterns, it is suggested that you forgo the Tanino treatment, as it will loosen up curls temporarily.

FAQs about Tanino Hair Treatment Side Effects
Yes, Tanino hair treatment is considered safe for color-treated hair. However, it can sometimes cause slight lightening or fading of the color since it works deep within the hair cuticle. To avoid this, it’s recommended to wait at least a week after coloring before doing the treatment. This helps your hair retain vibrancy and ensures the best results.
The effects of Tanino usually last between two to four months, depending on your hair type and aftercare routine. Using sulfate-free shampoos and nourishing conditioners can help extend its longevity. Environmental factors like the sun, chlorine, and frequent washing can shorten the effect. With proper maintenance, some people enjoy results that last closer to four months.
Tanino itself does not normally cause hair fall, as it is designed to strengthen and smooth hair. However, if your hair is already weak, brittle, or experiencing shedding due to health, stress, or chemical damage, it may feel like the treatment worsened it. Always consult with your stylist first to ensure your hair is healthy enough for the process.
Tanino treatment is not a chemical straightener, so it doesn’t permanently remove curls. Instead, it softens and loosens the curl pattern, making your hair easier to manage. You’ll still keep some curl or wave, but they may appear more relaxed. The exact result depends on your natural texture and how curly your hair is to begin with.
It is not recommended to apply Tanino at home, as the process requires skill and professional tools. Incorrect application can lead to uneven results or wasted product. A professional stylist will ensure that the treatment is evenly distributed, properly sealed, and safely applied. For best results and safety, salon application is always the better choice.
Side effects from Tanino are very rare, especially compared to harsher chemical treatments. Some people may experience mild scalp irritation, sensitivity, or a slight change in curl pattern. These effects are usually temporary and manageable with proper care. Following aftercare guidelines helps minimize risks and ensures healthier results.
If you have a sensitive scalp, it’s best to do a patch test before getting a full treatment. This helps check for any irritation or allergic reaction. While Tanino is gentle and formaldehyde-free, every scalp reacts differently. If you do experience sensitivity, your stylist may adjust the method or recommend extra soothing aftercare.
No, Tanino is formaldehyde-free, which makes it safer than many other hair-smoothing treatments. Instead, it uses natural tannins, amino acids, and proteins to nourish the hair while taming frizz. This is why many consider it a healthier alternative to keratin or Brazilian blowout treatments that may release strong chemicals.
When applied correctly, Tanino is generally safe and even beneficial for most hair types. It strengthens, smooths, and hydrates the hair instead of breaking bonds like harsher treatments. However, if your hair is already extremely dry or brittle, you’ll need extra conditioning care before and after. This ensures the treatment delivers the best results.
It’s best to wait at least one week after your Tanino treatment before coloring your hair. Doing it too soon can lead to faster fading or uneven results because the hair cuticle is still settling from the treatment. Waiting ensures your color looks fresh and lasts longer while keeping your hair healthy.
