Hair Product Allergies


Hair care products are a pretty common item found in the modern woman’s (and man’s) life. There are products that cleanse, condition, smooth, style, protect and thicken the hair. These products go through rigorous testing to ensure their safety for use by people of the recommended ages and generally-speaking, they are helpful and rarely harmful.
However, some people find that they have intolerance for some products that others have no difficulties using. This intolerance typically takes the form of an allergic reaction, the severity of which may vary.
In order to discuss these types of reactions, we should discuss briefly the nature of allergic reactions in general to help us create a baseline of understanding of the terms and concepts involved.
Allergy Basics:
An allergy is simply defined as “a harmful immune response to an antigen that is not in and of itself harmful”. This means that the substance that triggers an allergy may not be specifically harmful, but that the body with which it comes in contact has an immune response to the substance which is harmful. There are four mechanisms found in allergic reactions. These are:
   • Immediate Hypersensitivities
   • Antibody-Mediated Cytotoxicity
   • Immune Complex Disorders
   • Cell-Mediated Hypersensitivities
Of these mechanisms, the first and forth (Immediate and Cell-Mediated Hypersensitivities) are the ones most likely to occur in connection with using hair care products (or any other food or product). The second (antibody-mediated cytotoxicity) and third (immune complex disorders) usually relate to longer term and innate health conditions, such as Rh disease in newborn babies, Myasthenia Gravis, Lupus, and varied Serum sicknesses and disorders.
The hypersensitivities are those that are generally reactions to the antigens that are either ingested (inhaled, swallowed) or contacted via the skin and absorbed in that way. These can produce histamine reactions (such as hayfever and asthma) or dermatitis such as the rashes of hives and poison ivy.
What this Means:
Now, we could get bogged down in the details and biology of allergic mechanisms and responses, but to keep things simple, this means that with any hair care product (since that is what we are mainly concerned with here) some individuals may have a sensitivity to an ingredient within the product that creates a harmful result.
These responses are specific to an individual, and depend on that individual’s specific sensitivities and the specific biochemistry of the individual. In other words, one woman may try a product and have no issue with it whatsoever, while her friend may try the same product and develop a rash. Or even if two people are sensitive to a product, one person may have a histamine reaction to the fragrance of a product causing them to undergo an asthma attack, while the other develops a painful rash after applying the same product.
The level of sensitivity (in fact the presence of sensitivity) can depend on factors like other substances and interactions, hormone levels, diminished immunities, or underlying illness. Women especially can be subject to changes in their sensitivity to products because of their bodies’ constantly-changing hormonal balance.
Girls in puberty, women undergoing menopause, women experiencing menses, and women who are pregnant all may experience reactions to products that they have used before, or may find that - during certain times in their lives – products which they previously couldn’t tolerate no longer affect them.
It is also a fact that sometimes you can develop sensitivity to a substance as a result of prolonged or repeated exposure to that substance. So, the hair gel that you had been using for years could be the cause of the mysterious itch and redness on your scalp simply because your body has developed sensitivity to it.
How to Use This Information:
At first read one would think that using a hair care product (or anything in our world) becomes a gamble, and in some ways it is. But, rather than be alarmist, think of this as a way to understand how to deal with the things that may crop up when you are dealing with your hair care products. If you begin experiencing irritation or unusual symptoms after starting to use some new product, obviously discontinue using the product.
However, if the symptoms occur and you can’t identify the cause readily, then try eliminating all the products until the symptoms abate, and add them back in one at a time so that you can isolate the cause/trigger. And as always, if you have severe reactions/symptoms, see a medical professional for assistance.

As always, see your doctor when you have any skin irritation or allergic response.}
