SerumScoop: Tips, tricks and news
Canities is the fancy word for premature greying of the hair, and most people have some amount of greying, from very sparse, to fairly widespread.
The color, density, and styling of hair have a colossal bearing on one’s self-esteem, especially in today’s times where a person’s first impression may turn out to his or her last impression. However, increased longevity of human life means that we spend an increasing proportion of our lives sporting signs of aging on our scalp. The most dramatic age-related change in hair is the onset of hair graying or canities, which is the gradual age-dependent dilution of hair color to gray or white, also known assenile canities (canities (L.), canus, hoary, gray). The graying of hair occurs due to an admixture of normally pigmented, hypomelanotic, and amelanotic melanosomes. White hair is the endpoint of graying. The age of onset of senile canities appears to be genetically controlled and inheritable. The average age for Caucasians is mid-30s; for Asians, late-30s; and for Africans, mid-40s. A good rule of thumb is that by 50 years of age, 50% of people have 50% gray hair. 
The darker the hair color, the more noticeable early graying will be. Particular hair colors are associated with some ethnic groups. The Fischer–Saller scale, named after Eugen Fischer and Karl Saller, is used to determine the shades of hair color [Table 2].  Majority of the human population (80–90%) fall into the U to Y category (dark brown/black hair) of this scale.
WHAT HAPPENS DURING PHYSIOLOGICAL AGING (CANITIES)?
The type of hair fiber keeps on changing with age. Neonates... have unpigmented lanugo hair while adults have short (mostly pigmented) vellus hair or fine pigmented intermediate hair and long terminal hair shafts. Similarly, surface morphology also shows variation with age, particularly with the reduction in the cuticular scale size. The synthetic capacity of hair bulb melanocytes is maximum during youth. An average scalp hair follicle usually receives 7 ± 15 melanocyte replacements from an outer root sheath reservoir to the hair bulb, which occurs in the first 45 years preceding the onset of gray hair. Different theories have been suggested for the age-related gradual loss of pigmentation. This includes exhaustion of enzymes involved in melanogenesis, impaired deoxyribonucleic acid (DNA) synthesis, loss of telomerase, loss of antioxidant mechanisms, and anti-apoptotic signals. Table 3 shows various changes that take place in a white hair bulb during canities. The net result is that fewer melanosomes are incorporated into cortical keratinocytes of the hair shaft. Cessation of pigment production by melanocytes in the hair matrix area surrounding the dermal papilla is a slow process resulting in slow outgrowth of graying hair at the pace of normal hair growth. All hair bulbs do not decrease pigment incorporation in the growing hair at the same time giving “salt and pepper pattern”to the scalp hair.
It has been observed that hair graying pattern depends on gender, age of onset, and smoking habits, with smokers having higher chances of having canities. Temporal area is involved in males first while in females, it is the frontal area. Age of onset also affects the area of involvement; parietal and occipital areas are involved in patients of young age while frontal area is involved in late onset group.
WHY DOES PREMATURE CANITIES OCCUR?
Premature canities is a common cause of referral to dermatologists. It occurs most commonly without any underlying pathology, but is said to be inherited in an autosomal dominant manner. It is different from poliosis which is circumscribed hypomelanosis of hair. The diseases associated with poliosis are given in Table 4. The pathogenesis of premature canities has not yet been clearly elucidated. A hypothesis that pH and cysteine level of melanosomes play critical roles in determining the course of mixed melanosomes leading to dark, light, or red hair phenotype has been proposed because of the diversity of human hair pigmentation. The role of pH in controlling mixed melanogenesis has attracted much attention as it is seen that tyrosinase activity is progressively suspended by lowering the pH, with a shift to more pheomelanin phenotype.[8-11] Concentration of cysteine in melanosomesis another control point in mixed melanogenesis. Chemical hair straightening is done by alkaline disruption of the disulphide bonds in the cortex of the hair shaft. It causes considerable damage to the hair because of the pH (9–12) of the chemicals leaving the hair dry and fragile. In a questionnaire-based study, Shetty et al. reported that 22% of the cases experienced graying of hair also.[8,12] There is definitely a role of trace metal ions in hair pigmentation. Copper ions are required by tyrosinase at its active center; thus, it is likely that copper ions in melanocytes are necessary to maintain normal color. Fatemi Naieni et al. compared the mean copper concentration in patients with PHG and controls and found lower mean serum copper concentration in the cases.
Data suggest that oxidative stress can also play a major role in the premature aging of skin and hair. This theory has been widely accepted these days. Reactive oxygen species (ROS) or free radicals, generated by a variety of internal and environmental factors may result in direct damage to various cellular structural membranes, lipids, proteins, and DNA. To combat these free radicals, our body has endogenous defense mechanisms such as antioxidative enzymes which include superoxide dismutase, catalase, glutathione peroxidase as well as non-enzymatic antioxidative molecules like vitamin E, vitamin C, glutathione, and ubiquinone. The production of these endogenous defense mechanisms decreases while that of free radical increases, resulting in aging.
APPROACH TO MANAGEMENT OF PREMATURE CANITIES
...Recent experimental work indicates that cinnamidopropyltrimonium chloride, a quaternized UV absorber, delivered from a shampoo system, is suitable for photo protection of hair, while simultaneously providing an additional conditional benefit on hair, Solid lipid nanoparticles have been developed as novel carriers of UV blockers for use on skin and hair, offering photoprotection on their own too by reacting and scattering ultraviolet radiation (UVR).[ 24]
Recent advances in the management of aging hair and scalp are anti-aging compounds. Shampoos are largely ineffective as anti-aging agents due to water dilution and short contact time, and antioxidants such as vitamin C and E in these preparations protect fatty substances in the shampoo from oxidation, and not the hair.

HERE'S A NEW SOLUTION TO PREMATURE CANITIES
New RevivHair REV with Grey Hair Reverse and Hair Stimulation is a novel leave-in serum that targets greying hair three different ways, all without the use of colorants and dyes.
It's one of the first products to combine award-winning new ingredients Greyverse and Darnkenyl to address both the appearance of grey and thinning hair:
GGB Rating: 5/5
ABOUT REVIVHAIR PLACODE BOOSTER SERUM:
This amazing leave-in serum is claimed to be a great addition to your haircare routine in order to reduce hair loss, encourage hair growth, and develop healthy hair follicles. Apart from this it also helps in strengthening the fibre against breakage and thickening the existing hair strands. Formulated with the most eligible hair growth peptides this serum can be used by men and women both.
REVIVHAIR PLACODE BOOSTER SERUM REVIEW:
RevivHair Placode Booster Serum comes in set of five glass vials with a syringe which can be used for applying the serum on to the scalp. The serum in the glass vial is tightly sealed and though it looks thick in texture it gets applied very well on to the scalp. Each vial consists of 6mL of serum, you need to use 1mL of serum every day. Using the syringe you can draw out exact 1mL of the serum and can apply it all over the scalp and massage it on to the scalp. The serum gets absorbed immediately and does not feel sticky or heavy. I preferred using it daily at night. If you are washing your hair daily, you can use it every morning after washing hair as well. It would be better to keep it as long as possible on to the scalp.
The best thing I observed about using this serum was that immediately within 2-3 uses my hairfall was reduced by 80 percent. Moreover I also observed better texture in my hair after using it for more than 2 weeks. About hair growth I observed that my hair partition did look much dense compared to what it was couple of weeks ago. RevivHair claims that the serum consists of highly stable and highly pure biometric peptides which is derived from bacterial fermentation which stimulates hair growth, thickening of hair and reducing hairfall.
I could genuinely see the difference in my hair density and texture. I would recommend this serum for anyone who is facing hairfall or hair thinning. Currently the product is available at discounted rate of USD 44.00/- and can be bought from here.

Being a new mom can be one of the most emotionally rewarding — and challenging — experiences a woman faces. And while you may have anticipated your body to go through a whirlwind of changes, you may not have expected your hair to start falling out in clumps.
Also referred to as postpartum hair loss, telogen gravidarum, and telogen effluvium, excessive hair shedding after childbirth (which would occur anywhere between two and four months after giving birth) can affect between 40 and 50 percent of women, according to statistics from the American Pregnancy Association.
“When a woman is pregnant, she has a lot of extra hormones in the body, including estrogen,” says Christine Carlan Greves, a board-certified obstetrician and gynecologist in Orlando, Florida. “The estrogen helps protect us from losing our hair. Then when she has the baby, there’s a sudden change in the hormone levels, including a drop in the estrogen. And this shift can cause a response in the body that may affect the hair cycle.”
In fact, Greves adds that breastfeeding can also contribute to hair shedding because it increases prolactin levels (the hormone produced in the pituitary gland that is responsible for breast milk production), which is associated with hair loss as well.

Renowned beauty blogger evaluates RevivHair Stimulating Serum with Redensyl, Peptides, Growth Factors, and Stem Cells:
"After about three weeks, I started noticing where my hair was the thinnest, that it was starting to get fuzzy and the hair was starting to grow again. After the fourth week, there was a big difference in the fact that the "peach fuzz" regrowth turned into actual hair that is now covering those bald spots I had! I can now wear my hair up without embarrassment and I owe that all to RevivSerums! They have an amazing product that works! "

Do you have hair loss or hair shedding?
If you’ve been noticing more hairs on your pillow or hairbrush than normal, you may worry that you have hair loss. You could actually just be shedding more hairs than normal. Yes, there is a difference.
Hair shedding often stops on its own
It’s normal to shed between 50 and 100 hairs a day. When the body sheds significantly more hairs every day, a person has excessive hair shedding. The medical term for this condition is telogen effluvium.
Excessive hair shedding is common in people who have experienced one the following stressors:
- Lost 20 pounds or more
- Given birth
- Experiencing lots of stress (Caring for a loved one who is sick, going through a divorce, losing a job)
- Had high fever
- Undergone an operation
- Recovering from an illness, especially if had a high fever
- Stopped taking birth-control pills
Most people notice the excessive hair shedding a few months after the stressful event. For example, a new mom can see excessive hair shedding about two months after giving birth. The shedding usually peaks about four months after giving birth. This shedding is normal — and temporary.
As your body readjusts, the excessive shedding stops. Within 6 to 9 months, the hair tends to regains its normal fullness.
If the stressor stays with you, however, hair shedding can be long lived. People who are constantly under a lot of stress can have long-term excessive hair shedding.
Hair loss differs from hair shedding
Hair loss occurs when something stops the hair from growing. The medical term for this condition is anagen effluvium. The most common causes of hair loss include:
- Hereditary hair loss
- Immune system overreacts
- Some drugs and treatments
- Hairstyles that pull on the hair
- Harsh hair care products
- Compulsion to pull out one’s hair
If you have hair loss, your hair will not grow until the cause stops. For example, people who undergo chemotherapy or radiation treatments often lose a lot of hair. When the treatment stops, their hair tends to regrow.
If you suspect that a treatment or drug is causing your hair loss, talk with your doctor. …
Other causes of hair loss may require treatment. Many people who have hereditary hair loss continue to lose hair without treatment. A woman who inherits the genes for hereditary hair loss may notice gradual thinning. Men who have hereditary hair loss tend to develop a receding hairline or bald patch that begins in the center of the scalp.
Treatment helps many people who have hair loss, but not everyone. A dermatologist can tell you what to expect.
Dermatologist can distinguish between hair loss and hair shedding
If you are concerned by the amount of hair falling out, you don’t need to suffer in silence. You can turn to a dermatologist for help. These doctors specialize in diagnosing and treating the skin, hair, and nails. A dermatologist can tell you whether you have hair loss or excessive hair shedding. Some people have both.
A dermatologist also can find the cause or causes and tell you what you can expect. Effective treatments options are available for many types of hair loss. The sooner treatment begins, the better the prognosis.
