The term ‘pH level’ is thrown around a lot in today’s society. We hear about the pH levels of household cleaners, the pH level of a fish tank, the pH level of baking soda…. But what about your hair? Did you know that your hair has a natural pH level, as well? Did you also know that this pH level is affected by the hair care products you use everyday? I sure didn’t!

The Importance of the pH Level
As many people will know, the pH level tells you how acidic or basic something is. For example, battery acid has a pH level of 1 and is VERY acidic. Bleach, on the other hand, has a pH level of 13 and is VERY Basic. A pH level of 7 is Neutral and includes things like blood and water. Your hair and skin are covered with a very thin fluid mixture of oil, salt and water called the mantle, which is naturally slightly acidic. The typical pH balance of hair is around 4.5-5.0.

So, what does this mean in regards to hair care products? The closer the pH level of your shampoo/conditioner/styling product is to the natural pH level of your hair, the more healthy and beneficial it is to your hair. Using a product that causes the pH level of your hair to drop can make it very basic can cause your hair to look dry, frizzy and become very brittle and easy to break. This is why using cleansers, such as baking soda (pH of 9) or even just water alone (pH of 7), can be very damaging to your hair with repeated washes.

What is the solution?
A common solution for balancing out the pH of baking soda is coupling it with apple cider vinegar, a natural base. However, often times these ingredients don’t perfectly balance each other or are unevenly mixed, resulting in some hair being treated with overly basic materials, while other hair being treated with acidic materials. You can read more about our verdict on the ‘No Poo’ method in this recent article.

Instead, we recommend choosing hair care products that match the natural pH level of your hair.  Balanced shampoos also protect your hair’s natural oils, known as sebum, rather than stripping it away, as is often the case with synthetic products.

Choosing the right hair care products that match your hair’s natural pH ensures the continued health of your hair’s mantle and gives your strands a healthy environment to grow healthy, strong and beautiful!

The Shampoo pH can Affect the Hair: Myth or Reality?

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.

There’s help for those who are experiencing hair loss. … You no doubt have heard of the two FDA-approved medications — Propecia and Rogaine — that are designed to help combat hereditary hair loss, but you don’t know which one is the most effective or best suited for you.

Propeciavs. Rogaine: Which Works Better?

Minoxidil is a medication that's commonly marketed under the name Rogaine, and finasteride is marketed under the label Propecia. You might use either Rogaine or Propecia to help treat hair loss. Talk with your physician before you use these medications for hair loss, because they both pose certain health risks, drug interactions and side effects.

Function
Rogaine and Propecia both inhibit hair loss while promoting hair growth, explains the University of Pittsburgh Medical Center.

Rogaine is an over-the-counter treatment used primarily for treating androgenetic alopecia, also called male- and female-pattern baldness, and alopecia areata, an autoimmune disease. Rogaine appears to make hair shafts thicker and increase the number of hair follicles, notes the University of Michigan Health System.

Propecia requires a prescription. It is used to treat androgenetic alopecia specifically in men. It affects male hormones that cause hair loss by blocking testosterone's conversion into dihydrotestosterone, or DHT.

Applications
Rogaine is a topical treatment that comes in the form of a foam, lotion or liquid spray. It is available in a 2 or 5 percent concentration solution that you apply to your scalp twice each day.

Propecia is a pill taken by mouth once daily or as directed by your doctor.

Timeframe
Rogaine topical solutions can take up to four months of daily use to show maximum effect, notes the University of Pittsburgh Medical Center. If you don't see a significant change in hair loss or growth after six months of use, you might want to try a different remedy. Unlike Propecia, Rogaine might generate new hair growth that's much thinner and shorter than your regular hair.

Noticeable results from taking Propecia can occur in as little as three months or up to one year. If you stop using Rogaine or taking Propecia, your hair loss will likely resume, and new hair growth will stop, because these treatments don't usually have any effects beyond active use, the Mayo Clinic points out.
 
Side Effects
Both Propecia and Rogaine can cause some side effects. Rogaine can cause itching, dandruff and skin irritation, cautions the University of Michigan Health System. Also, women who use Rogaine could grow unwanted facial hair. Propecia can cause erectile dysfunction, low sex drive and other sexual-function problems in men. Propecia might also cause drug interactions, so talk with your doctor about any other medications that you're taking.

Warnings
Propecia poses serious health risks to women and children. Pregnant or breastfeeding women shouldn't take or even handle Propecia pills, and men taking Propecia should use birth control with their partners to prevent pregnancy while on the medication, warns the University of Pittsburgh Medical Center. Propecia could cause serious birth defects. Women using Rogaine who also take estrogen-containing medications like oral contraceptives or hormone replacement therapy could experience enhanced hair growth, notes the University of Michigan Health System. If you're pregnant or breastfeeding, you should ask your doctor before using Rogaine.
