Continue reading this investigation of aHOWTO and you will discover what is baking soda shampoo foruses, benefits and drawbacks.

Uses and benefits of baking soda shampoo

Bicarbonate shampoo is one of the beauty trends nowadays. For example, there are countless articles, videos, and recent web posts claiming that baking soda has properties whitening, exfoliating, deodorizing and cleansing. For this reason, it is believed that it can provide us with the following benefits for hair:

  • Remove excess fat from the scalp.
  • Reduces dandruff in oily hair.
  • Cleans the scalp of residue from other products that may have been left on the hair.

However, it is important to know what bicarbonate really is in order to understand the true scope of this substance in beauty care.

Bicarbonate is a compound made up of sodium, one of the elements in salt, as well as carbon and oxygen. The common presentation is a fine, white powder with a salty taste. One of its characteristics is that it has a pH level of 9, which means that it is quite alkaline.

But is baking soda safe for hair? Yes, if it is used properly and the impact of this compound on our body is taken into account. That is, it all depends on what and how we use it. Let’s see the most common uses of baking soda in hair and how to apply it in your daily beauty routine.

baking soda to clean hair

Nowadays, it is fashionable to prepare a shampoo of bicarbonate of soda, water and, optionally, essential oils to wash the hair. However, it is not the way in which specialists recommend using this compound to clean hair.

By making a paste of baking soda and water to rub into your hair, you subject your hair to an erosive and abrasive experience that can irritate the skin and cause rashes. This is due to the high level of alkalinity of this substance.

This was established by research published in the International Journal of Trichology, a science dedicated to the study of hair and scalp. The more alkaline a shampoo is, the more likely it is to damage the hair cuticle and break it, in addition to causing the dreaded frizz.

So how can you use baking soda to clean your hair? It should be used as a powder, like a talcum powder. that is called dry cleaning. In this way, you will also take advantage of the properties of baking soda to absorb bad odors.

How to dry wash your hair with baking soda

  • Sprinkle the bicarbonate on the head and distribute it gently.
  • Do not rub it against the scalp.
  • Then brush it gently to remove the excess.
  • It is important to note that the level of acidity in baking soda can be detrimental to hair. For this reason, we do not recommend using this product daily, especially if you suffer from hair pathologies, oily hair or very dry hair.

    Baking soda to lighten hair

    Another popular use of baking soda is lighten or bleach hair. For this, a mixture like the previous one is prepared, but instead of using tap water, hydrogen peroxide is used.

    Actually, it is the hydrogen peroxide or hydrogen peroxide that does the job of bleaching the hair, something that it can do very well without the baking soda. Remember that there are several volumes of hydrogen peroxide according to the level of dilution, and in its natural form this solution is quite aggressive. For this reason, those with higher volumes act faster and deeper than those with lower volumes.

    Do you mean peroxide is much better for lightening hair? Yes, and also less aggressive with proper care. If you do it at a specialist place with a professional colorist, they will not only lighten it, but will also do their best to protect it from the damage caused by discoloration.

    Baking soda for gray hair

    Gray hair is the result of the loss of melanin in the hair follicles. This loss can be caused by factors such as age, genetics, the use of harmful chemicals, poor diet or stress. If you have prematurely gray hair, it is best to consult a dermatologist to act directly on the causes that have caused them.

    However, some people use baking soda as home remedy for gray hairas its composition is believed to help keep the pH of the hair balanced and maintain its pigmentation.

    There is no evidence that this compound stops graying, but if you want to try it, you can follow these steps:

    baking soda for dandruff

    Another common belief is that the baking soda with apple cider vinegar controls dandruff and promotes its disappearance. Since vinegar has antifungal properties, it can help control dandruff, as long as it is due to fungal-related causes.

    However, the pH of the scalp ranges between 4.5 and 5.5, that is, slightly acidic. It is precisely this acidity that helps control the appearance of fungi. If we subject it to a product as alkaline as bicarbonate, it could alter its balance and dry it out.

    For this reason, baking soda can be used to treat dandruff caused by excess oil in the hair. If you want to know how to use it, you will only have to:

  • Mix 2 teaspoons of baking soda with water until it forms a thick paste.
  • Apply it on the scalp with massages.
  • Leave for 15 minutes and rinse with plenty of warm water.
  • baking soda for oily hair

    In general, people with very oily hair can benefit from the use of baking soda, as it is responsible for cleaning and removing excess oil from the scalp. However, the best way to use it will always be in a dry wash, as we told you in the previous section.

    Baking soda for colored hair

    Opinions about the effectiveness of baking soda to remove hair dye they are divided. While one group recommends it, another points out that they tried it and it was not effective.

    In any case, colored hair should be treated like damaged hair, especially if it has previously been bleached.
