The best dry shampoo is like the wand of your fairy godmother, granting precious moments of your life back in a spritz of magic dust. On those hectic mornings where there’s no time for coffee — let alone a full-on wash-and-blow-dry routine — dry shampoo gets you out the door looking fresh. We set out to find the best and after 45 hours of research and 17 product tests, Klorane Dry Shampoo With Oat Milk stood out as our favorite.

In our search, we read dozens of articles, scoured top lists and recommended brands, and consulted with experienced stylists and other industry experts. We sorted the aerosol sprays from the powders, and tried the expensive ones as well as the DIY alternatives we made in our own kitchen. The best ones soaked up oil, added volume, and left our hair smelling fresh. The worst were messy to apply and left our hair a chalky white.

Based on our research, we designed a method for reviewing dry shampoo, focusing on the most popular, competitively priced options. With our methodology in place, we narrowed a list of more than 50 dry shampoos down to the top five.

That moisturizer your friends swear by left your face red and scaly. The cleaner you've been using for years to make your bathroom sparkle made your hands itch and burn.
 
For some people, the chemicals in shampoos, cosmetics, and detergents can trigger allergic skin reactions.
 
Causes
These reactions -- what your doctor calls allergic contact dermatitis -- happen when your immune system overreacts to chemicals that are normally harmless. They can be in products you're exposed to over and over, like cleaners, colognes, hair dyes, and personal care items.
 
Even if you've used them before, you can still have a reaction.
 
Cosmetics and personal care products have a lot of potential allergens, things you could be allergic to:

• Fragrances in soaps, colognes, deodorants, body creams, cosmetics, detergents, and tissues
• Preservatives and antibacterials, added to many liquids to keep them from spoiling
• Substances added to thicken, color, or lubricate a product
• Chemicals in permanent hair dyes and other hair products
• Formaldehyde resin, an ingredient in many nail care products
• Sunscreens, often found in cosmetic moisturizers, lip balms, and foundations

 
Symptoms
Your skin is one of the first places where the warning signs can show up. They often appear 24 to 48 hours later, but can start as late as a week after you come in contact with the irritating chemical.
 
Each person may have different chemical allergy symptoms. Some of the most common are:

• Red skin
• Scaly patches
• Blisters that ooze
• Burning or itching, which may be intense
• Swelling of the eyes, face, and genital area
• Hives
• Sun sensitivity
• Darkened, "leathery," and cracked skin

 
The symptoms tend to be worst where you touched the thing you're allergic to. If you get the allergen on your finger and then touch another part of your body, like your face or neck, you can set off an allergic reaction there.
 
Other conditions can cause similar symptoms, so see your doctor to find out what the problem is.
 
Diagnosis
Often your doctor may be able to diagnose your allergy by doing a physical exam and asking you about your symptoms.
 
Sometimes, he may suggest you see an allergist for a skin test, also called a patch test. The allergist places small samples of chemicals on your back and checks to see if you get a rash.
Keep track of your symptoms. It will help your doctor make a diagnosis. Note details such as:

• What you were doing in the 24 to 48 hours before your outbreak
• Any products you were using before the reaction
• How much of the product you were using and how often
• Where it touched your skin (even places with no symptoms)
• Symptoms you have or had
• Any previous skin reactions

 
Treatment
You'll want to identify and avoid the chemical that seems to cause your allergic reaction.

Most of us use some sort of hair product on a daily basis, and allergies to many of their ingredients are common.
 
While hair color is the biggest offender, other products like hairspray, conditioners and extension glue can cause redness, itching and even swelling in those with allergies. The problem is, many women and men experience these symptoms without knowing the exact cause.
 
As a dermatologist, I can effectively treat the allergy, but it often takes a while to determine the source of the reaction. Here are the most common hair products that cause reactions—and a few allergy-free alternatives.
 
Hair color
Whether you use hair color to cover grays or for highlights, if you’re allergic, you know it.
 
The main ingredient responsible for hair color allergies is paraphenyldiamine (PPD) and it can cause redness and swelling wherever the product touches the skin. Another offender is toluene (which can also be found in nail polish but most major brands have omitted it from their formulas).
 
I see many patients with hair color allergies, but there are alternatives that provide the benefits without the side effects. Vegetable dyes like henna cover grays on darker hair, and if you prefer highlights, the trendy ombre look is achieved by placing color just at the ends so it doesn’t come in contact with the skin.
 
Hairspray
In the case of hairspray, fragrance is most often responsible for allergic reactions like redness, irritation and swelling. Other ingredients that cause reactions include propylene glycol (which is often used to “seal in” moisture) and acrylates, which are used to form a film on the hair.
 
Though I wish I could recommend a hairspray that’s unlikely to cause a reaction, a better approach is to make a note when you have a problem and consider what products you used in the previous 24 hours. Then read those labels and see if you can identify the culprit. If you still can’t figure it out, see your dermatologist for patch testing so you can avoid the offender in the future.
 
Perms and straighteners
Treatments such as keratin straightening have been getting bad press due to side effects from the professionals who spend a lot of time around the fumes, but these treatments can cause allergic reactions when they come in contact with the skin — even if it’s only every few moments.
 
The main problematic ingredient in these treatments is formaldehyde, and it leads to itching, skin cracking and irritation in those with sensitivity. The problem with a formaldehyde allergy is that this ingredient can be listed many ways on product labels, so it’s best to consult your dermatologist if you react to these types of hair treatments.
 
Hair conditioner
Something as simple (and common) as conditioner can have side effects on the skin.
 
A very common ingredient like isopropyl myristate can aggravate acne, and it often comes in contact with the face, back and chest when used in the shower. If you have persistent body acne, check your labels, and be sure to wash your back and chest with a salicylic acid cleanser after washing and conditioning your hair.
 
Hair extension glue
Think about it … anything that’s designed to attach hair to your head (and withstand washing and tugging) might have some detrimental side effects on the skin. The main ingredient in hair glue that causes reactions is ethyl cyanoacrylate, so if you experience adverse effects, consider another hair extension technique.
 
Other options include thermal bonding and sewn-in extensions, and these eliminate the possibility of skin reaction.
 
When a patient is unable to isolate the ingredient causing their skin allergies, I often ask them to bring in their skincare and hair care products so I can take a look at what they’re using. In most cases, reading the labels and taking a thorough history is enough to pinpoint the source of the reaction and eliminate the product from one’s beauty routine.

BBC Radio broadcast an interview with an elderly academic, Dr. Clothier, who discoursed on the government's efforts to stop the spread of Dutch Elm Disease, which had been infecting many of England's trees. Dr. Clothier described some startling recent discoveries about the tree disease. For instance, he referred to the research of Dr. Emily Lang of the London School of Pathological and Environmental Medicine who had found that exposure to Dutch Elm Disease immunized people to the common cold.

Unfortunately, there was a side effect. Exposure to the disease also caused red hair to turn yellow. This was attributed to a similarity between the blood count of redheads and the soil conditions in which affected trees grew. Therefore, redheads were advised to stay away from forests for the foreseeable future.
