ABSTRACT Dandru is a very common skin condition that nearly all people experience at one point in their lives regard-
less of age or ethnicity. It aects the not just the scalp, but also the ears, eyebrows, sides of the nose, beard, and less
commonly the central (often hair-bearing) part of the chest. Dandru can aect any hair-bearing area or an area with even very small hair
follicles. Other names for dandru are seborrheic dermatitis or seborrhea. Malassezia ( formerly known as Pityrosporum) is a genus of fungi.
Malassezia is naturally found on the skin surfaces of many animals, including humans. In our project cause of dandru is studied by a daily
routine habits such as- Expose of hair in pollution , Quantity of water you drink daily , Exercise , Use of hair gel or dye , Diet , Fruits in diet ,
Use of hair oil etc . By doing the survey on daily routine habits , the data is collected and stastical interpretation of data is done with statistical
softwares like WEKA . WEKA is a data mining software used to identify the cause of dandru depended on daily routine habits.which helps in
identifying the causative agents of dandru. rough this survey we got that - People who drink more than 8 glass of water per day & do daily
exercise & eat fruits do not have dandru , ose who do not exercise daily & are non-vegetarian can have dandru , e shampoo pantene
and clinic plus are less eective for dandru than head & sholder etc.
Materials and methodology
Firstly we have studied dierent aspects of daily routine habits
which causing dandru and according to the referencef we have
collected , we prepared a questain array .We take the questions
according to the following ideas
• Water intake more than 8 glass
drink at least eight glasses of water per day,Not only is it great
for your overall health and wellbeing, it can also help in prevent-
ing and treating dandru. Being well hydrated keeps your skin
hydrated and prevents the skin on your scalp drying up and ak-
ing. It may not be the cure of all cures, but it proves again that
drinking more water never hurts.
Just as exercise can help energise the cells on our scalp, a quick
scalp massage can also get the blood owing to this area, there-
by helping to reduce dandru. “Try giving your scalp a gentle
massage once a week with a warm oil, such as almond, before
shampooing out,” suggests Nicky Clarke. “Massaging helps to im-
prove the blood ow around your head and this also encourages
hair to grow stronger and healthier.”
A senstitive scalp is a scalp that feels itchy and irritated.Several
factors,such as pollution, stress or even products that are too
harsh can cause the scalp to become increasingly sensitive.To ef-
fectively treat your scalp , adopt a good daily hair care routine.
e following foods are known to aggravate dandru:
Fatty Diets : Most contemporary diets, particularly those with
a heavy incidence of packaged or pre-packaged foods, are a rich
source of saturated fats. is type of fat is needed by the body in
smaller amounts. e daily requirement can be easily surpassed
if packaged foods are regularly eaten. e excess fat is stored in
the body that apart from promoting a tendency to gain weight
harms the body’s metabolic functions.
is is particularly applicable to the dandru problem. Such
fatty diets stimulate the sebaceous glands into producing excess
amounts of sebum. e overproduction of sebum acts as a cata-
lyst for various kinds of infections that worsen the dandru situ-
ation. is includes fungus like P. ovale that dwells in scalps with
excessive sebum levels. In this case, the scalp might appear oily,
but it can still harbor dandru due to the increasing infection
that causes decomposition of the skin’s cells, creating dandru
Spicy Foods : Excessive sweating in the scalp is an established
cause of dandru. is is because sweating increases the vulner-
ability of the outer layer of skin cells in the scalp, making them
susceptible to being easily scratched-o. Spicy foods are known
to induce sweating. is is because spicy foods tend to raise
the body’s temperature, inducing perspiration that is more pro-
nounced around the temple and the scalp. e sudden release of
sebum from the sweat glands on the scalp further irritates the
skin, causing a prickly feeling to develop.
Beverages : Dandru is commonly understood as a condition of
aky or dry scalp skin. is condition can be largely controlled
by regulating the hydration level of the body. us, foods that
aid the elimination of bodily uids should be consumed in mini-
mal amounts. is includes beverages like tea and coee that
are established dehydrating agents. Such foods stimulate fre-
quent urination and perspiration, lowering the body’s uid lev-
e following foods help to cure dandru:
Green Vegetables and Fruits : Green vegetables and fruits with
thick skins are reputed sources of soluble and insoluble ber.
e body’s ability to absorb water from the large intestine is
largely dependent on the overall health of intestines. If the intes-
tines are overwhelmed with compacted/hardened stools, an un-
wanted state of articial dehydration is established. is means
that the body is unable to absorb sucient water though the
individual may be consuming the appropriate amount of uids.
is form of constipation can be solved by consuming green,
leafy vegetables and fruits on a regular basis. While the soluble
ber helps in the motility of the intestine, the insoluble ber
presses against the impacted stools, alleviating constipation.
Vitamin-Rich Foods : Foods that oer a high concentration of Vi-
tamin B are critical for limiting the proliferation of dandru. Vi-
tamin B is needed by the scalp to heal and thus limit the crust-
ing of its upper surface. Simple foods like bananas, avocados,
beef, tuna, legumes and oats are rich sources of various types of
Omega-3 Fatty Acid Foods : Food items like sh (or sh oil) and
axseed are rich sources of omega-3 fatty acids. ese foods are
particularly recommended to dandru suerers whose dandru
is accompanied by excessively dry, bodily skin. ese fatty acids

• Collected 500 forms and enter to the WEKA software to get
the statistical interpretation of the data. Depended on dif-
ferent aspects the results are analyzed.
WEKA software :
Weka (Waikato Environment for Knowledge Analysis) is a popu-
lar suite of machine learning software written in Java, developed
at the University of Waikato, New Zealand.
e Weka workbench contains a collection of visualization
tools and algorithms for data analysis and predictive modeling,
together with graphical user interfaces for easy access to this
functionality. e original non-Java version of Weka was a TCL/
TK front-end to (mostly third-party) modeling algorithms imple-
mented in other programming languages, plus data preprocess-
ing utilities in C, and a Makele-based system for running ma-
chine learning experiments. is original version was primarily
designed as a tool for analyzing data from agricultural domains,
but the more recent fully Java-based version (Weka 3), for which
development started in 1997, is now used in many dierent ap-
plication areas, in particular for educational purposes and re-
search. Advantages of Weka include:
• free availability under the GNU General Public License
• portability, since it is fully implemented in the Java pro-
gramming language and thus runs on almost any modern
• a comprehensive collection of data preprocessing and
• ease of use due to its graphical user interfaces
Weka supports several standard data mining tasks, more spe-
cically, data preprocessing, clustering, classication, regression,
visualization, and feature selection. All of Weka’s techniques are
predicated on the assumption that the data is available as a sin-
gle at le or relation, where each data point is described by a
xed number of attributes (normally, numeric or nominal attrib-
utes, but some other attribute types are also supported). Weka
provides access to SQL databases using Java Database Connec-
tivity and can process the result returned by a database query.
It is not capable of multi-relational data mining, but there is
separate software for converting a collection of linked database
tables into a single table that is suitable for processing using
Weka. Another important area that is currently not covered by
the algorithms included in the Weka distribution is sequence
Weka’s main user interface is the Explorer, but essentially the
same functionality can be accessed through the component-
based Knowledge Flow interface and from the command line.
ere is also the Experimenter, which allows the systematic com-
parison of the predictive performance of Weka’s machine learn-
ing algorithms on a collection of datasets.
e Explorer interface features several panels providing access
to the main components of the workbench:
• e Preprocess panel has facilities for importing data from
a database, a CSV le, etc., and for preprocessing this data
using a so-called ltering algorithm. ese lters can be
used to transform the data (e.g., turning numeric attributes
into discrete ones) and make it possible to delete instances
and attributes according to specic criteria.
• e Classify panel enables the user to apply classication
and regression algorithms (indiscriminately called classi-
ers in Weka) to the resulting dataset, to estimate the ac-
curacy of the resulting predictive model, and to visualize
erroneous predictions, ROC curves, etc., or the model itself
(if the model is amenable to visualization like, e.g., a deci-
• e Associate panel provides access to association rule
learners that attempt to identify all important interrela-
tionships between attributes in the data.
• e Cluster panel gives access to the clustering techniques
in Weka, e.g., the simple k-means algorithm. ere is also
an implementation of the expectation maximization algo-
rithm for learning a mixture of normal distributions.
• e Select attributes panel provides algorithms for identify-
ing the most predictive attributes in a dataset.
• e Visualize panel shows a scatter plot matrix, where indi-
vidual scatter plots can be selected and enlarged, and ana-
lyzed further using various selection operators.
J48 Prediction model tree :
J48 implements Quinlan‟s C4.5 algorithm [QUI92] for generating
a pruned or unpruned C4.5 decision tree. C4.5 is an extension of
Quinlan’s earlier ID3 algorithm. e decision trees generated by
J48 can be used for classication. J48 builds decision trees from
a set of labeled training data using the concept of information
entropy. It uses the fact that each attribute of the data can be
used to make a decision by splitting the data into smaller sub-
sets. J48 examines the normalized information gain (dierence
in entropy) that results from choosing an attribute for splitting
the data. To make the decision, the attribute with the highest
normalized information gain is used. en the algorithm recurs
on the smaller subsets. e splitting procedure stops if all in-
stances in a subset belong to the same class. en a leaf node
is created in the decision tree telling to choose that class. But it
can also happen that none of the features give any information
gain. In this case J48 creates a decision node higher up in the
tree using the expected value of the class. J48 can handle both
continuous and discrete attributes, training data with missing
attribute values and attributes with diering costs. Further it
provides an option for pruning trees after creation.
